Running a gang in a mission can be challenging to remember who has what enabled.
One option would be to hide from the Tactical menu any skills which are in play and are not stackable (eg Preparation)
Another option (perhaps better?) would be to simply list all the skills/buffs/debuffs in effect at the time (shown on the fighter info screen).
I sometimes get a situation where I cannot jump or pick up an item because of “skill debuff”, but I have no idea which skill debuff it is, how I came about it, or how to get rid of it.....
