Always on top floating window

[JuniorJPDJ]

just a suggestion

Don't see how to implement this. Changing window type to keep always on top is illegal in Android - apps just crash, you should have this type set since the app start. So we could completely kill an app and restart it hooking on the way as system overlay / phone type, but it kills usability and potentially brings errors to working apps. Any ideas?

Restarting is an option, but how you said, it's killing usability.
At least I know it's not possible...
Thank you for reply ;)
