A QoL suggestion would be to have access to the inbuilt image editor in other areas besides the Item Editor.
Right now, the process of assigning icons to Skills, Status, currencies etc (besides importing one) is to make a dummy item, use it to make the image for the skill/status/currency/etc, then delete the dummy item.
Be nice if any areas that have the ability to set an image also had the little green + for accessing the image editor that items use.
