When only one custom icon set exists, selecting an icon causes a dropdown to appear that says, ‘Nothing found.’ This is confusing, as there’s no context for what the dropdown is supposed to do.
Only after creating a second custom icon set does the dropdown label change to ‘Move selected’, making its purpose more clear, to move icons between sets.
Suggestion:
To improve clarity, the dropdown should be hidden when there’s only one custom icon set, as no move action is possible in that state.
thank you for your suggestion. As it’s not directly a bug, I moved your topic to the Feature Requests / Improvements , but I’ve also created an internal improvement request for this.
