Since the host application doesn't support directories yet, something must be done to allow us to edit group level properties

Requirements:
TBD

Tech Dependencies:

There is probably a good case to argue for comparing files. Specially when PHash dredges up a suspiciously similar file to the one on screen. Let's create a mode that lets us dig a bit deeper.

This is one of those features that may make sense to exist in the base application. Building it in an extension is going to be a lot of work.

Requirements:

• Must create a new side by side mode
• Could implement synchronized zoom & move

Tech Requirements:

• Must be able to wrap the existing stage center, it doesn't make sense to implement this again
• Host must allow extensions to add modes and the ability to navigate. Or implement the mode itself

Add the ability to merge one group into another

Requirements:

• Must support combining one or more groups into another
• Must be able to trigger from gallery mode
• Could create a new mode dedicated to setting ordering before saving the merge

Tech Dependencies:

• Opening menus / adding menu items in gallery mode
• Selection awareness for extensions / menu commands
• Extension to trigger navigation

People make mistakes, groups gets created wrong, a bug in curator's sorting logic, etc. Would be a lot friendlier to fix these problems in the UI instead of a command line.

Requirements:

• Must be able to assign a new index to an existing file
• Could implement drag and drop to make interaction idiot-proof

Tech Requirements:

• Extensions must be given some sort of write access to the files list
• Host application may need to support drag and drop and ephemeral ordering

If the response sent from curator is too long, it will be read out in multiple steps. Need to switch to a builder pattern in service.ts
