I'm waiting for Cosmic to be merged into NixOS stable which I learned is just around the corner (May). I'm super excited because Cosmic seems to strike a sensible balance between polished, full-featured, make-everyone-happy mainstream DE and performance-oriented tiling WM.

Although I've never tested the Alpha, I have a feeling that I might finally make the switch (from Gnome) on my daily driver once it's mature enough.

I used COSMIC for a while and really liked the core DE. Being able to easily move between stacking and tiling is great and the workspaces work well. The new multi-monitor stuff sounds good.

I do not love the included apps. The terminal was ok but a bit of a memory pig. It is Alacrity based. All early days though and of course other apps work great with it, though with mixed UI.

Early versions leaked memory but apparently that was related to a bug in Glibc that they have now worked around.

COSMIC is definitely a really neat desktop, and I'm looking forward to the stable release!

I have had the alphas installed and usually give it a go for a day or two each revision. Currently there's definitely some oddities regarding graphical glitches, such as after suspending the system - but I like where it's headed.

For me right now the biggest roadblock is the lack of a night light mode (blue light filtering). I've gotten so used to relying on it in other desktops.

I do have some crappy $20 blue light filtering glasses, but they're... Not great or comfortable to wear for any extended amount of time. And my monitors' built in color shifting mode is also pretty lackluster.
