The new tactical UI shows a bar with up to 7 spells/items/actions available.
It would be a great help if this bar could be resized to hold more options, for example by allowing the player to grab the end of it and drag it to the right, like a similar bar works in Dragon Age: Origins.
Failing that, or in addition to that, it would be helpful if the player could reorder the spells in the bar, so that the most used spells can be placed there.
