Hello, I found a compatibility issue with the Universal Importer.

When I installed this plugin, any interaction with LordOfTheToolbars started creating unnecessary icons on custom panels. It is solved by disabling the Importer, but at first it was not clear what was happening, then I figured it out myself. So I'm just informing you that such a case took place.
