Emulator

It would be nice to have a live display of buttons, like some streamers already use as a third party tool, but integrated into Dolphin so that it shows the Wii buttons instead of the keyboard keys that I set for them.
I livestreamed recently and it was probably a bit confusing to see keys like WASD appearing in my keyboard display instead of up left down right. This would also solve the problem of having to find a key display program (I found only two for Linux, one didn't run and one isn't ideal) and the problem of having to record more than the game window, thereby increasing the video dimensions without much gain.
Showing a proper Wii remote tilt instead of my TFGH keys would also be much nicer to watch.
This feature could also help to verify speedruns (mainly human, maybe also TAS).
