Swapping between weapons or items adds all the actions/skills in an automatic order.
If we have already placed the same action/skill previously on a specific spot - it should remember where we placed it and make it show there!
Example:
Unarmed Strike -> Replaced on common bar slot A6
Equipping any weapon removes the Unarmed Strike
Removing weapon -> Enabled Unarmed Strike but puts it on the first available slot -> Should remember the Unarmed Strike to be at bar slot A6 !
Same applies to all actions/spells etc !
