I finally got around to upgrading PopOS and the new Cosmic desktop environment.
It's very promising! I love the vision. It's fast, accessible, and slick. The emphasis is on giving the user control over screen real-estate and interactions with advanced window layout, tiling, and navigation features, both assisted and manual, with lots of customization options and the ability to mix different modes of interaction fluidly.
Unfortunately, it still has some rough edges. I was really hoping they'd be sanded down by now, but not so much. I've been having troubles with quirky focus and mouse tracking issues, unexpected layout changes, and limitations for configuring behavior in the new default apps.
I love what they're trying to do, and optimistic many of these issues will improve, so I'll stick with it. But maybe I should join their user discussion forum and start reporting bugs...
