As others have s pointed out, it looks like as a relatively new user you’ve tried a whole lot of stuff meant for advanced users and managed to completely avoid the tried and trusted Linux mainstays that have been around forever. Like KDE, Gnome, xfce, and most user friendly distros like Linux mint.
Tiling WMs for example are best for people who want to spend weeks if not months working in their configs and dot files, and are privately designed for keyboard and not mouse use (hence the WM you identified as not having a button to close the window)
But I’m curious for you end up doing these things as a new user. Is there a lot of bad advice going on out there?
That’s easy; because Ikey Doherty wanted to make one.
He abandoned Solus years ago as the project became something he didn’t enjoy anymore, and wanted to start a fresh project closer to his philosophy of engineering everything.
When a person starts a new project it’s usually because they want to.
So the key here is, in classic Ikey style, they want to use/develop all their own tools. engineer everything themselves to be exactly what they want it to be. This is what suits them and Ikey has the chops to do this better than most.
He started this project about 5 years back as Serpent OS, rebranded it last year as he got to alpha release stages.
