I am using Plasma 5 with a heavily customized Latte Dock configuration with lots of applets.
I am unsure if some of the applets (e.g. global menu, window buttons, window title) will still work with Plasma 6, or whether Latte Dock will work.
How should I prepare for the upcoming Plasma6 upgrade so that it would not break my configuration? Should I revert back to default KDE configurations before the update?
I will deactivate all plasmoids that are still running on Plasma5. I then set everything to Breeze default. Only then will I update to Plasma 6. I have had problems with plasmoids that were not ported in time. But I can’t tell you which plasma version that was.
I tested Plasma 6 with a (very buggy) Neon ISO in a VM. My custom Plasma 5 Window Decorations worked fine with no modifications, I just dropped it into ~/.local/share/aurorae/themes (note that I had to create that directory), and my custom Plasma 5 theme also worked fine with no modification after dropping it into the System Settings “Plasma Style” GUI.
latte-dock-git still works well for me in Plasma 5.27, and the Plasma panels don’t have as much capabilities. I hope things will get better with Plasma 6.
