Hello people, While debugging a problem with a duplicate instance of Orage, I renamed one .desktop file and was surprised I now had 3 instances in the 'Add new Items' list. I moved that desktop file to another directory entirely, and the entry in the item list remains. I have the impression the list detects _adding_ entries, but not removing items. Thanks for the good work!
It checks if the binary/library still exists, so renaming the desktop file won't work since all the desktop info is extracted and stored in the panel, so not required any more.
