OS: OpenSuse Tumbleweed with KDE. Icon Theme: Reversal
I used the Latte Dock before but since it didn't play nice with Wayland and is basically unmaintained now, I simply transformed a KDE Panel into a Dock. I use a KWin Script called "Panel Auto Hide" to make the Dock disappear when window hits it.
How's Tumbleweed treating ya? I find that when it comes to rolling release I'm very much comfy with the Arch-based distros.
Liking the layout as well, I honestly might look at this or something similar. IDK, the old Windows-style layout is getting kinda boring, want to spice up my workflow a bit.
I recently changed from EndeavourOS to Tumbleweed and I couldn't be happier. Very fast and stable.
It comes with more, lets say, "bloat" than an normal Arch-based distro, but nothing that you can't remove if you feel like it.
If you use KDE, it has one of the best integrations in my view. You can use zapper (tumbleweed version of pacman), and even though you loose AUR packages you have OBS (OpenSUSE Build Service).
There is very good documentation for it also, but nothing beats Arch wiki.
