It must be possible to enter destination address and amount of STR and send it via the Stellar network

• Display edit fields for address and amount
• Send via api

• announce migration in social media
• announce migration within app
• migrate button: STR -> XLM

On the wallet tab:
Show/Hide button for secret

• Build Instructions for Windows
• Build Instructions other OSs
• Levels of Contribution
• Link to Stellar-Client on GitHub

In the wallet tab, provide a way to export keys, e.g.

• write json file
• import the keys from such file
• import the keys from a qr code with json coded keys

add missing issues

Scan a qr code and fill address (and amount) in edit fields
See this example for getting started

see templates/tab-about.html
When an <a href="http://some.external.link"> is clicked, the target site opens within the wrapper browser. This would be ok. But navigation back is not possible, so you are stuck an cannot get back to the app!

• disabled the link to gh-pages for the moment
• nice solution would just display like any link, but open in system browser
• perfect solution would handle this once and for all within the app, e.g. with a new value for the <a target="..."> tag

Did not try the proposed solution from the ionic forum, yet!

should behave the same way as in the stellar browser client:
https://github.com/stellar/stellar-client/blob/master/README.md

• new view for displaying contacts (done)
• display all contacts (done)
• text input for filtering (done)
• add new contact from scratch (done)
• edit a contact (done)
• fill send tab from contact (done)

If started for the first time, the app should create stellar keys and use them for any transaction afterwards.
A Following issue should

• either use the wallet-service in order to retrieve keys for an existing account
• or proper encryption with local password + backup-functionality for the created key, ...

• drop unnecessary resources
• drop unnecessary files from lib-folder
• ...

A new button (let's say in the about-tab) for reporting errors:

• automatically retrieve as much device information as possible (manufacturer, model, android version, screen resolution, ...)
• retrieve the apk version (should somehow be the value from config.xml)
• other helpful things like date and time, connectivity etc, suggest a category
• checkbox if the functionality worked correctly in a previous version
• Explain to the user, that all information is used exclusively for analyzing the error, nothing else
• Transmit the information (e.g. mailto [email protected])
• nice to have: display the apk version within the app

Apply the multiplanguage concept desribed by Andrew McGivery.
Start with

• English (default)
• Deutsch

Nice to have: tutorial (even for non-developers) how to contribute a new language

• new edit field for destination tag
• determine whether receiver requires destionation tag (account flags)
• hide edit field by default, show only on demand or if receiver requires destination tag

Use jekyll to provide more than the start page on github pages:

• Everything that is currently posted in Stellartalk.
• Data privacy statement, that can be linked in the google store entry
• qr code for immediate download of the app
• ...

• path payment
  • determine destination currencies
  • remind that I can always send assets to the respective issuer
  • calculate possible paths (streaming?)
  • do the payment

• Additional input field to specify the destination currency
• if possible, query the network for the possible destination currencies and display in a dropdown or something

#18 (export/import keys) should be done first.

On startup, a login screen should popup in order to enter stellar credentials and retrieve keys from the stellar-wallet service.
The keys must be available for any stellar api calls during the apps lifetime.

It's currently using an old beta release:
"ionic": "driftyco/ionic-bower#1.0.0-beta.11"
This should be changed to the latest stable
"ionic": "driftyco/ionic-bower#1.1.1"

Or maybe even use the Bower repository for this.
"ionic": "1.1.1"

Update: seems that using any other version than the current beta 11 will mess up the UI big time. Haven't checked out why yet.

Update 2: in tabs.html the class is:
<ion-tabs class="tabs-icon-top"> but in the beta 11 version it's at the bottom. Is this intended? Changing the class to "tabs-icon-bottom" will put it back at the bottom (as in the beta) for v1.0.0. When using v1.1.1 there's no UI at all (except for a back button text).

Update 3: So it seems that the UI doesn't get messed up big time if v1.0.0 is used. The difference between beta 11 and v1 is that apparently v1 uses the default location for the location of the tabs. At the top for Android and bottom for iOS etc (http://ionicframework.com/docs/api/directive/ionTabs/). It's allowed to override this, so it's up to you to decide if you want to override it or don't...?

Using v1.1.1 does mess up the UI as nothing is visible anymore, but that's the next step to fix :)

maybe reorganize all code to a more feature related structure

It is hard to get Dollars, Euros, Yen and Yuan out of people's head. So I would suggest the following feature:

• integrate a currency conversion service
• possibilty to choose a display currency (supported by the conversion service)
• for all stellar amounts indicate (additionaly) the corresponding value in the display currency
• wallet tab: balance, (maybe recent transactions, but prio 2)
• send tab: available amount, payment amount

display all balances

In the about view, section 'Contact' there is a mailto:[email protected] link. It works in the ripple emulator but not on my android device (Galaxy Tab 4).
Did not try other emulators or platforms yet.

• wait for stellar sdk issue to resolve federation address
• resolve contact names first

• remove everything that remains from old websocket
• remove websocket plugin
• call other plugins into question
• Use Account.isValidAddress()
• call healthCheck into question
• analyze upgrade to higher versions of
  • ionic
  • cordova

fill trx tab with n most recent transactions. (e.g. n=20)

ngCordova is still there, I guess it is the same, but should be replaced in bower than

Use Ionic directives instead of plain html on all tabs.
Try to support copy/paste (at least where addresses/keys are displayed) (Prio 1)
Very nice to have: swipe to change tabs

The user's STR-Balance should be displayed in the Wallet tab.

• It should be emphasized somehow, because this is the most important information on this tab.
• Some refresh mechanism is required to keep the balance up to date. If automatic refresh is complicated, a user action for refreshing is acceptable

In the transaction view use a recent transaction to create a new contact.

• use on-hold to open dialog
• in the dialog show name, address and memo, prefill address and memo from transaction
• for debit trx use receiver to fill address, for credit trx use sender

Generate a QR-code for the user's stellar Address
nice to have:

• add a text field for desired amount and include as parameter

• change internal account representation as to allow multiple balances (decide whether STR is one Balance among others or remains a special balance)
• UI Concept for multiple balances (merge different issuers or not). Refer to official client.

• simple payment (done)
• destination tag (done)
• if unfunded -> use create account instead (done)

Currently the account reserve is hard coded to be 20 STR. This is fine as long as users use freshly created accounts. However as import of existing accounts is now supported, this might lead to confusion.

• Check if the correct reserve is part of the account_info response.

Regularly check if connection is established.

• indicate connection state (at least in the wallet tab or globally)
• automatic reconnect (may 3 attempts or something)
• manual reconnect

• in the send view. resolve contact name to address (done)
• in the trx view: reverse match address(+memo) to contact name
• nice to have: auto completion when typing the address in the send view

If websocket communication is not available, fall back to long polling.
Prio depends on how widespread the problem occurs

On some devices transactions are displayed again and again!

• not reproducible with emulator on testnet
• when duplicated transactions appear, they also modify the account balance (which indicates it is a problem with the stream, not the initial fetch of transactions)
• closing and reopening the app removes all duplicates and the account balance is correct.

Need to specify at the same place

• send request
• handle response (success and error)
• fallback for any error
• ...

If inflation destination is not set and account holds enough reserve, set inflation destination to centaurus.
Solve #30 first.

In the Wallet tab display the user's recent transactions

• Somewhere below the balance
• Fix amount (e.g. 10 or 20 most recent entries)
• keep in sync with balance when updating the view
• nice to have: dynamic paging (load more when user scrolls down)

We need unit tests to achive a reliabitlity, adequate for software dealing with digital assets.

scan tx envelope qr code and submit it to live network. would be super useful for cold wallets

single contact or full address book

• via file system
• via social sharing plugin

In the receive tab, add a button "share" with options to send the stellar address via

• WhatsApp
• SMS
• ...

track payments

• update account balance (done)
• show in trx tab (done)
• how to navigate from effect to operation and transaction (done)
• update account sequence number (done)
• display effects in chronologic order (done)
• nice to have: use http://momentjs.com/docs/#/displaying/fromnow/ to show relative time of transaction

• Before sending payment, query the network for all (source) currency options.
• Display all possible options and make the user choose one (consider ionic actionsheet for this purpose)

The address remains "loading" all the time.
First we have to find out, whether this is a api version issue or device specific or something else like environment/branding.
Try to reproduce it in emulator first. --> No Problem in emulator
Maybe its a mobile provider issue (o2 Germany).

Seems a better term to me that should fit on the screen.

Maybe move About to the top right too with just an information icon?
