I landed the first part of this work in main - everything seen in the video below. I.e. it's keyboard-only for now. Gamepads will have to wait a bit more, there are a few more things to solve there first. I also made it autofocus the next row after binding the current one, like in OpenEmu. People usually want to rebind multiple controls at once, and IMO it's more seamless this way I only have diagrams for NES and SNES right now, will be slowly filling them in one by one. I also changed how scrolling is done on mobile - the controller diagram is now pinned at the top and doesn't scroll, so I can get rid of the annoying popup label at the bottom and do it exactly same as on desktop instead. I also have partial implementation of per-game overrides, just need to handle the case where a game has multiple controllers available to it.
