I wish you did, but you don't. I've been on three desktops technically; GNOME 2.xx, GNOME 2.xx but modified as my own desktop and xsession, and MATE. All of them foundationally GTK 2, two of the three options impossible. Then there came the change where certain GTK 2 apps aren't feasible because you can't just change gnome to mate in config files and have it work.
Now with 19.04 I cannot install my preferred (and less error-prone) global EQ without pulling in prior libraries which no longer exist in Canonical's Disco repos. It's BS.
I'm tired of change. All the moving's wearing me out. It makes Windows' interface design, even with the modern changes they've made feel more stable. At least, ten years from now I'll still know how to use Windows.
