[DEV] Interface options A & B

Yes, they should have 2 type UI

And the 3rd option is the third party UI support

somebody might anti your idea because of they're using gamepad and don't want keyboard-mouse users play better than them

That's more a symptom of another problem that I doubt they will look at: Character movement as is doesn't seem to be smooth enough for keyboard+mouse to be on par with a gamepad.
