This spell bar is designed to be used with the number pad with spell 1 being number 1, spell 8 being nmber 9 and skipping number 5. I find this hand since I have numberpad enter as target closest NPC and number pad + as sit/stand and finnally number pad - as hotbutton number 1(pet attack or melee attack depending on the char). Th background is set to transparent to keep from blocking the view. To move the window, just click between the gems.
