It is looking very promising. I was a bit skeptic at first, but everything is looking quite polished. I am wondering, Will the terminal have support for images, in similar way to kitty or iterm2? And also another thing, Will the file manager has a three pane view? (macos finder, or ranger (tui) style)
I know those two things are missing from gnome equivalents, and are quite handful for productivity, at least for me. Being more advance than gnome, but simpler than KDE would make COSMIC appealing for a lot of people I think.
