Too many skill bars available will break the game in my opinion - it is supposed to be some kind of strategy and planing involved. You can already see the enemies ahead on the map before you engage them and choose skills appropriately. If you chose bad combination of skills - it should cost you AP during the fight to change them to something more useful.
I would agree with 2 to 4 more skill slots added but entire bar/bars... that would be too much imho.

There is no issue for me in its current form BUT:
1. can the squares in the inventory (each square holds an item in it) be made a little bit smaller?
2. can the inventory be resizable? Drag and expand the inventory so more items will fit on the screen without the need to scroll down through them?
