SUMMARY Desktop files (*.desktop) have three properties: Name, Description (GenericName) and Comment. If the Description is missing, a description won't be shown when the user hovers over the app's icon in the task manager. Menu Editor's desktop file doesn't have a description. So a description could be added, something like "Menu Configuration".
Since this is a Plasma-only application with a generic name (not a "brand" name), it doesn't really need a description, so this bug report can probably be marked as RESOLVED INTENTIONAL, but I'll wait for a developer to make that decision. The same was decided for Welcome Center in BUG 504401.
After doing a bit more research here, I realize I was wrong. It's actually the opposite: we should fix Task Manager (bug 504431) rather than reducing useful metadata. The metadata can't assume the anything about the presentation layer, so we should be good citizens and set everything.

Git commit c8dc4886675d13a76ed5f33f41e78ca4bd7b14cd by Nate Graham. Committed on 21/05/2025 at 19:38. Pushed by ngraham into branch 'master'. Add GenericName to .desktop file It'll be the exact same thing as the app name, but that's fine; it's for the benefit of any presentation layer that wants to show generic names rather than brand names.
