I think double keybinds would be a feature that can't really hurt anyone/be helpful for a lot of people. I am a lefty person so I use my tablet with my left hand, which means that I press keys with my right hand. Sometimes though I feel like using my mouse, but since I use my mouse with my right hand I have to either move my keyboard to a completely awkward spot, or just have to go my keybinds and change them. This is not an issue at all, it takes merely seconds, my point is if the feature could just be there for some of us to save time it would help a lot. If users do not like this feature, have the second set of keybinds be unbinded by default.
