Fully-themed distros?
These days it's hell to theme your distro. You have to deal with 5 different toolkits: Qt 5,6 and GTK 2,3,4/Libadwaita. Granted, GTK2 and Qt5 are being phased out, but you still occasionally run into apps that use them. And even if we ignore GTK2, that still means you need themes for GTK 3, 4/Libadwaita and Kvantum. It's hard to enough to find themes consistent across all these, let alone ones you would actually like.
In addition, personally I am tired of theming my OS manually. One of the reasons I'm currently using a distro that comes with default Gnome theme and the corresponding adw-gtk3 pre-installed is that all I had to do was set up Kvantum manually with LibAdwaita theme. I don't love Adwaita, but what I love even less is spending hours customizing a newly-installed distro when I already have a lot of setting-up to do.
So, my question is: are there any distros that come with a pre-configured theme that covers all 5 toolkits?
