Hi, I just wanted to ask, what does the main tab on top left of the screen in config window mean?

Also if it doesn't mean anything, or is reserved for future use, I have a suggestion.
It would be very cool, if you could have multiple like profiles/presets, each profile would have it's own keybinds.
For example I would have a World Edit profile, where I would have world edit related keybinds and then other profiles.
You would also be able to swith the profiles with a keybind.
