[FEATURE] Make Mod App Buttons accessible in all states

[Micrologist]

Are there concrete plans for how to make mod app buttons accessible in other states?

The VAB has its own APP. BAR that could be integrated into.
The KSC and the Tracking Station don't their own App Bar, but as far as I can see the "inflight app bar" is still loaded with the parent gameobject disabled, maybe it could be forced on with only mod app icons enabled?
The main menu has no app bar and would need its own implementation.

In theory it might be a good idea to have mods be able to specify on which screens they should be accessible (you wouldn't need a Maneuver Node Editor in the VAB or an Alarm Clock in the main menu), but since mod windows persist you could run into issues where you can't close a mod window that you opened earlier.

Needed locations

• VAB
• KSC
• Tracking Station
• Main Menu

You could provide a toggle to choose between quick deployment and deterministic propagation delay, this should be opt-in. think that could be solved by user-specific invites. Yes, all of the app buttons would be able to set by mod creator. We would be able to be user-specific, and the buttons would be able to set by mod creator. This code would return the build number and last deploy timestamp, which would allow adding multiple buttons or lists at once, by user/list/button ID. We would be able to be user-specific, and the buttons would be able to be user-specific. This could be achieved by having a dynamic rate limiting implementation.

Currently working on a separate general AppBar library mod that would provide this functionality
