What possible sense does this make?!? Why would you NOT want to see powers that you DO HAVE?
I run my Quick Key control bar at the maximum size so that I can access any and all that I have currently assigned to my ship....or character/team. Why would I want to HIDE any of them?
I don't want to see my BO powers on my tabs since they have their own tab. Often, the BO powers end up on my power bars and clutter up everything. So by dragging (a copy) of the BO Powers on tabs 8-10, I dont see them on my power bars( tabs 1 and 2).
It's the same with abandon ship and Transward, I don't need to "see" them on my main power bars, so they go to tabs 8-10 where they stay.....out of sight, out of mind.
Also, it seems when I switch weapons, their icon winds up on my main tabs. So, since I don't want to "see" them on my main tabs, they go to tabs 8-10 as well.
It's not a perfect solution, but it's a good temp fix till the devs get this problem solved.
