to keep things simple, a default user profile will always be created. Adding new user profiles will make a user profile selection dialog when starting the app.

a selection of avatars should be available to allow children to easily select their profile.

Part of the keypad are covered when using blackboard/Math! When holding the device in landscape mode.

This happen only on devices with small screen such as webOS phones (Pre, Veer, Pixi).

When doing operations with numbers, we learn in school to start from the right and proceed to the left.

While Blackboard/math is a flash card type of app, and it make sense to start from left to right, some users may prefer to enter number from right to left.

We'll add an option to write the numbers from right to left.

This will fix issues with iOS devices.

analytics collection was quickly thrown in.

should create/end activity for each game start/end. Also need to send an event when user press 'back'.

it would be nice to have some way to display some analytics in the app itself (how many users currently using the app, total problems solved, ...)

when holding a small screen device (Pre, Veer) in landscape mode, the start button is not clickable because it is under the footer.

The layout of the screen will have to be change to better accommodate smaller screens.

Sometimes... When the application load really fast, there is a blank screen instead of the application UI.
This seems to happen more on fast Pre (2, overclocked).
Probably due to firing stageReady a bit too fast.

to allow to draw on the board

if the user taps on the answer screen while it's in it's ease in animation, he gets a blank screen.

Currently, the CSS for larger screen are selected when Blackboard/Math! run on a high density device like the Pre3. This yield a small user interface that is not very useable.

Should also check if there is a network connection before loading it.

a system of reward when the user achieves certain stage in using Blackboard/Math! Like after 100 problems solved, X hard problems solved, ...

rewards will take the form of fun math learning videos or animations.

Some user are distracted with the screen transition after answering a problem.

The screen transition will be remove. The answer will appear in the screen with a smooth animation without the full screen transition swipe.

This should also fix #16

rework the difficulty levels to more closely match grade levels for kids.

to keep the ui simple, we'll have 1-2, 3-4, 5-6 grades. With maybe an addition of a higher difficulty level for high schoolers and adults.

record problem runs in order to displays stats, track progress, retry runs.

For example, on Nexus 7 (2013), In landscape, the problem and the keypad are too large. But in portrait, they are too small.

in addition to having congrats displayed on screen, we could have some sounds to add some emphasis.

There is no hint that the user must tap the screen when the problem answer is displayed.

This confuse first-time users.

An hint should be displayed to tell users to tap the screen to display the next problem.
