It is KDE Plasma, after I tweaked it to have a Mac/GNOME-like layout with Papirus icons.

      Blumoop a very modified gnome was my first guess cause it still looks like gnome🙂 you need a compositor or a bubbling cauldron for the floating taskbar effect? Or one of those WM packages? Love it

          brent lol I made "KNOME", since I was a GNOME user, and before that Cinnamon. I like how in Plasma you can make it your own with the customization features, used to not Plasma because I would have a bad experience with bugs, but Plasma 6 has been smooth for me so far.

            This shows us: KDE is very flexible
            You can turn a KDE into a Gnome
            But never a Gnome into a KDE
            Great
            I know why I'm with KDE

            6 days later

            now looks something like this (but kinda worse imo)

            KDE Plasma | Icon: Kora | Style: Breeze | Colors: Automatic from wallpaper

            I have Krunner enabled on WIN key so i can just press it and start typing to find whatever it is i'm looking for, apps to open etc. I guess similar to how Gnome works.

            Power button top left i have set to open Application Launcher in Dashboard view. But i rarely use this menu as i handle most tasks through Krunner

              Nice to see my icon theme in use at someone else 🙂
              I see I missed the trash can 😮

                  Pjol Dashboard view search function is very disapointing. I like the aesthetic but Krunner and Kickoff is way too good to be replaced by it. If only it uses the same back-end as kickoff and krunner.

                    anyways sticking to materia, since i liked it from the start of my solus journey
                    and edited the libadwaita theme, so it would fit the surroundings.
