I find myself dropping key items like crossbows/swords on accident midfight when playing gamemodes like MCCI Sky Battle.
If this was implemented, it would have these customisability features:
- how long you have to be out of combat before you can drop items again
- setting an alternate keybind to drop while you are combat tagged if you want that like ctrl+q
- being able to set what forms of damage can combat tag you or not
