I guess a lot of tablet and pen users have trouble adding a beatmap to a collection and having to switch to the mouse just to right click while holding the pen(mostly the pen button cannot be used because tape grip or just removed them), its a bit anoying to do that. Not all tablet models have buttons on the surface to adjust the buttons in OTD. So I would like the context menu button to be customizable to any key in keyboard or add a button to add collection in the options menu
