Been using this for close to a year (wrote about it here when it was still called Dank Material Shell: https://tedium.co/2026/01/29/niri-danklinux-scrolling-window...); it is endlessly slick, and I think good enough to help mainstream Niri.

It also just added official support for atomic distros like Bazzite; it was previously kind of an annoying gap given the popularity of those distros.
