I got this application after a Fedora release upgrade. Before I used plasma-pk-updates ???, a small applet that notify updates and permits to update in one click. Personally, I like to see which packages are updated before to go. Discover is slow and seems to hang when it looks for updates. Feedback is minimalist, so ??? I enabled automatic update in KDE Settings, but ??? Also, I noticed a lot of strange behavior that look like wrong QML codes. When you click on about, the page render and then rerender with a glitch because something changed a little on the page. Same for configuration. It seems to be everywhere in the application. When you click on the vertical tabbar, two buttons can be momentarily pressed. There are also a lot of UI looks and feels to improve. Anyway, dnfdragora looks like a 15 years old application.
Please note this is not a place to vent. If there's something specific that isn't working for you, please open a bug report for that thing and we'll work together to figure it out.
