Adding rows to raise the hotbar and make room for more abilities works but often gets in the way of the viewport, especially when dealing with finicky loots or clicking just that one pixel to hit an enemy NPC when the "path is obscured".
Simple suggestion - there's plenty of screen space to the right & left of the hotbar for it to grow wider and gain more columns, and this would help. Also, being able to set additional columns to better group abilities and spells would also be great to keep the icons clean and well-grouped.
Thanks!
