So! After I've done some edit, aura element seems to be working pretty good and I'm really happy with current result
Thanks to lightspark!
The one problem that I'm currently having is that the number of buffs actually exceeds the size of buffs frame.
What I mean by is the following:
Each buff size is set to 20x20 with 2 pixels spacing between two buffs while the buffs frame is set to the size of 100x100. So, the fifth buff will exceed by 8 pixels.
Should I set the size of buffs frame by manually to prevent this? Or is there any options to set number of buffs per row?
