As a mage I need lots and lots of hotbars on my screen to shuffle between wands and weapons, cast spells, activate/deactivate metamagic feats, etc. The current situation is a little unforgiving of misclicks. If I click the border of the hotbar in combat it moves the bar, even if only a little. It would be nice if, just as we can choose between vertical and horizontal bars, we could lock bars into position when we are happy with their locations. This way on a misclick nothing happens (or better yet the border helps the spell being cast).
