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. Emoji Selector's desktop file doesn't have a description. So a description could be added, something like "Emoji Utility".
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 78c7ab617a3e3ccc7dd5bb97bd3774029c08d14b by Nate Graham. Committed on 22/05/2025 at 13:00. 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.
