Can I use different panel setups in other desktops/activities?
When I create a new desktop or activity, it seems to use the same panel setup.
You cannot use different panels per activity (or desktop) in Plasma 5, but I know there was some discussion about the feature possibly being available in the upcoming Plasma 6 release.
You might be able to use different instances of Latte Dock, which isn’t exactly the same thing as Plasma’s panel, but I think it would work.
I don’t think Latte Dock is an active project anymore. I guess I will wait for KDE Plasma 6 and see what happens.
