I like to watch videos published by Nick from The Linux Experiment. In the latest video he talks about the developments in the new Cosmic, The quality of life touches and polishing of KDE, and the apps coming to gnome (like snoop). It is all really cool and I can't wait to try them all :)
Xfce is just so nice and simple.
Looks great, I used the wallpaper myself for a while. What theme/icons do you use?
