Hi! Just a small thing I noticed.
When you right click an empty folder, the menu says "Delete Folder...", but in German it says "Ordner löschen......"
The ellipses don't seem to be part of the text I can translate in Localizer

I have translated the text to Danish, so it should be in there somewhere. I would have a look, but it seems like there are some issues with logging on to Localizer.
And now I got access..
In UI ressources, try looking at mnuDeleteConnection_GroupMultiSelect
