Translations are provided in *.arb* format.
Some keys have descriptions
(indicated by leading @-symbol).
Descriptions should not be copied into the translation itself.
Currently only English is supported (app_en.arb),
but German is planned.
Apparently weblate merged .arb support at some time,
so it would be nice to enable community translations at some point.
The screen allows the user to change the default permission set,
that applies to every member (but not the owner nor the admins).
This screen is only accessible by the owner,
admins or members with the changeAdmin permission.
Done in preperations for rooms,
and the ability to edit rooms.
Will later be used to hide/show certain elements,
when the user does not meet the criteria
(permissions / admin / owner)
