I offered them a suggestion that actually would cover 36 action slots instead of 30. It was meant for joypad, but i think it can be used at kb aswell. The basic was allowing to set 9 actions to each button (cross, square, circle and triangle...and yep, i use PS2 joypad) so during battle you could access them by arrow + button combo. Those who played Tales of Fantasy (very old) would think its a similar mechanic to the one used at that game (also similar to super smash bros skill combo system)...but there they were related to only one button and here i suggested using all 4 buttons during battle.

So, basically, you would have access to an action by pressing just one of the buttons (default cursor position) or holding one of the 8 directional arrow positions and pressing the button.

But its like i suggested them...it not being an action bar...it actually being a different widget that can be swapped with action bar so players can use the one they feel that fit their needs the best. IMO hacing multiple widgets with multiple mapping/configurations/mechanics would add flexibility to the game.
