Right now the systray has a very ugly delay when opening applets like WiFi or sound. Up to 1.5 seconds (!). This doesn't happen with the applets bare in the menu bar, so there must be some sort of negative interaction there between the systray code and applet code.
This is on a bog standard KDE install too.
I don't like Gnome's high and mighty attitude either, especially because it chases people away from making bug reports or contributing. And when 90%+ of your users uses a particular extension (Dash to Dock), maybe make that behaviour integrated and the default.
At this point my hope is squarely aimed at PopOS' COSMIC environment.
It's fine giving lot of customization but the default got to be good, and at the opposite (gnome) it's fine to give no customization option as long as it's well thought out and makes sense.
Sadly, it's neither the case.
The best I could find was cinnamon desktop, they're not too bad.
But I do think some of the systray things are overly complicated. E.g. why does the volume widget list all audio outputs and inputs by default?
On the other hand some things are really great. E.g. which other DE lets you adjust the screen brightness (the real one via DDC/CI) from the systray, or start video screen capture by pressing print screen?
KDE is definitely better than gnome at this point.
Now I'm using Cinnamon until the bug gets fixed which I enjoy too but it doesn't come close to the ease of use of KDE. And when I say ease of use on KDE I refer to the fact that out of the box you can pretty much do everything you need to without having to search for extensions or hunt for settings, someone already thought of what you wanted to do and made it straightforward to do. Sure it's overwhelming to be presented with a lot of things at once e.g. the screen capture UI but when you need to do something that's not the base case it's easy to see that the UI has got you covered.

Both of these work for me on Gnome 49.
