Some ideas :

For the skill bars : give us some hotkeys ( like F1 F2 F3 ) to select the bar

For easier target selection : give us a hotkey to pause the animations. It could be automatic when a skill has been selected and it needs a target.

Concerning the formations :
- give us a button to link/unlink all ( plus hotkey +/- )

After a combat :
- don't end the combat as soon as the last ennemy is dead. Allow us to decide to do it when it is safe ( poison, burning ... ).
