Same here (on Fedora), coupled with Kando (which recently got Niri support) for mouse gestures, shortcuts and macros it's a total powerhouse.

Sadly I can't seem to find a config I like for waybar, if anyone has any tips or dotfiles please share them!

I never found a config either and decided to go without any sort of a bar. That was two years ago and seems to be working fine for me.

I wrote a couple of tiny IPC watchers that send notifications on workspace change and whatnot. The rest is handled by centerpiece:

My waybar just shows the time in the center, my network status, and my battery health. It’s very minimalist. I went without entirely for a while, but I missed having the time there at a glance.
