This is a pretty easy and simple suggestion, but a fix that would be much appreciated.
As of right now the custom icon item (healer, collector, attacker, defender), that can be purchased through a custom donation, is equipped in the cape slot. This means that you are unable to wear a cape while an icon is equipped. This doesn't make much sense as the icon is not associated with the cape in any way and wouldn't cause any graphical errors if one was equipped.
My suggestion is to change it from the cape slot to the ring slot. Rings are not visible so this would not interfere with any other equipped items, allowing players to have the ability to still wear capes, etc. in addition to an icon.
