Sounds reasonable to me.
1) "Kill on long-press" is a Lineage feature. Not sure how exactly it is implemented, but we will look into it.
2) So you want to prevent other apps from rotating the screen? AFAIK "Rotation Control" starts a background service which monitors the screen state. We tried to solve it more elegant, but obviously there are apps which ignore system settings. I'll try to figure out more details about the system logic - maybe there is another way of preventing such behavior.
3) Yes, sorry. And "Recovery" shows "Factory data reset..." :innocent: These are localized system messages, so we would need to modify it in all existing languages. I hope we will have enough resources for such changes in future :blush:
