I was a BIG fan of Regolith, super sensible defaults and smooth onboarding experience.
But with the V2 it seems the config is now split in 100's of files (ok not 100 but more than one). I loved the fact that with original i3(Regolith) I had to back up 1 file for my i3.
I now moved to Manjaro-i3. Been happy so far.
The key (on Ubuntu at least) is to simply go with the standard Ubuntu installation and then switch to a custom .xinitrc-based X session that starts i3. That way, you can still fire up the usual Gnome dialogs (e.g. for printers) when you need to. (Obviously, some settings related to configuring your desktop – e.g. key bindings – will no longer work.)
You can actually use a desktop with i3 as the window manager and use the existing settings menu if you prefer. Not every desktop supports this but for example kde does.
Stealing some tray icons (volume, clipboard, KTeaTime, network), I built the setup I'll probably use for another 7!
Thanks to everyone involved! Tiling WMs rule!
