I’ve seen several questions asking about why their shortcuts are messed up, how to change them, etc. Editing the shortcuts for the hot bar is a nice, streamlined, in-app method… but it’s so easy to do that it happens accidentally all the time.
Editing the hot bar shortcuts needs to be either more difficult, more transparent (and thus more obvious), or both. To make it more difficult, perhaps only enable that while in build mode, or through a menu somewhere. To make it more obvious, a confirmation dialog could require user input.
For what it’s worth, the message that currently displays when you attempt to set a shortcut that’s already used in another hot bar action is fine for what it does, but I think it wouldn’t be obvious enough to cut down on accidental rebindings if you were to use it for that purpose.
