Since i use large number of custom icons, i've noticed a few things by now.
- There is no proper way to (re)sort User Icons, i would love to be able to create sub categories for my custom Icons and rearrange the order of icons already imported
- Right-clicking in the state-icon categories window will show a tooltip with a small typo: "availale" (should be "available") as seen in the attached image.
- Adding a new state icon will usually add the icon to end of the icon list, but sometimes right inbetween for a reason unknown to me.
- There is no way to resize the State Icon window or scroll to the left, but the right-most / 10th column of icons will be hidden by the window border and you are only able to "scroll" leftwards by using arrow-keys.
The attachement shows the cut-off icons in the right column.
