For the size those were for testing purpose only. It will be up to marco to size them as he wishes, as those are all softcoded (a new txt file defines which states should be tracked, whether they are considered a buff or a debuff, and which icon it should display). Same goes for colors and what not. The screenshot mainly meant to show off the concept. The display can also be toggled on & off with a hotkey.
I also plan to add a tinting functionality so that different buff/debuff types can be differentiated by colors (like gold icons for auras, for example)
Various types could be active auras, very long-lasting buffs, short-lasting buffs, curses, potions, etc.
