Created attachment 105490 [details] screenshot of problem There's a somewhat annoying UI papercut with the device notifier when more than one USB drive is connected. The first device displays fine in the UI. The section expands and collapses normally to show/hide the "Download Photos with Gwenview" and "Open with File Manager" options. However, with additional devices, the sections don't collapse—they maintain the full height needed to show the Gwenview and File Manager options but do not display these options until the user clicks on the device listing.
Stupid QtQuick Layouts bug, I also sometimes have it not collapse properly after unmounting...
