I'm running my avatar on Ñ and Ç, so while it could be a useful gimmick, it still works from when the system is aware of said transition, which kinda is a hotkey dilemma. I have the hotkeys mapped in a controller that Veado can't read (SPOILER: it's a quite old model that most modern software doesn't care about so I found a good use to it that way, and personally, I prefer that way, as it doesn't get in the way with games due to it being a controller recognized by the games themselves.
Of course, being able to code the program would be far more useful than adding more hotkeys to the mix, which is kinda my complaint, as there's very few unintrusive hotkeys available. State categories also would make some ideas seamless. For example, with my avatar, I have the option to change the clothes, which means I have to hide my avatar, load the veado file for the other version, and then reveal it so the interface doesn't show (the UI is perfect, but UIs absolutely get in the middle of the purpose of vtubing so having a sort of second window for the UI controls would be absolutely appreciated in a future update)
