[Android] Full screen issues

[m-reiter]

I am not completely happy with the way full screen is implemented in the Android app. My 2 issues with it are:

• Full screen is only activated in landscape orientation. What is the reasoning for this? I would much prefer to also be able to view portrait size pictures at maximum size in full screen.
• Currently, full screen is set by calling windowInsetsController.hide(WindowInsetsCompat.Type.statusBars()) which keeps the navigation bar visible. I find that distracting when viewing a picture. Would it be possible to change that to windowInsetsController.hide(WindowInsetsCompat.Type.systemBars())?

I realise that taste might differ in this matter, so the best option IMO would be to somehow make that configurable.
