Screen orientation setting / locking
Though most native Jolla apps do not support anything other than portrait mode, almost all Android apps in addition to some functions like the native video player support both landscape and portrait mode, and in these apps it would be nice to be able to lock the orientation to either portrait (for most apps) or landscape (e.g. for playing videos) mode.
Update: it would be optimal if there was a system-wide default setting of: portrait, landscape, or locked/unlocked (depending of which tge orientation changes when user turns the phone and a/or individual applications orientation can be set independently of system-wide default
