ok, try this:
in the design that contains your primary actionbar, look for the actionbar-feature and change the "States Type" to "Custom", then in the field "Custom definition" enter this:
Code:
[bonusbar:1,stealth] 6; [bonusbar:5] possess;
it should look like this:
with this change, the bar should switch to bar7 if you are stealthed instead of bar6, and should display things like vehicle abilitys and other special abilitys you get when you controle something that is not your character (like the daily quest in molten front where you fly around as a bird and have to collect other birds, or the up/down stuff on the quest where you have to climb on a tree to throw down the little bears)
