I’ve been running Artful aka 17.10 on my laptop for maybe a month now with no real issues and thats thanks to the awesome Kubuntu developers we have and our testers!
My Current layout has Latte Dock running with a normal panel (yes a bit Mac-y I know). I had to build Latte Dock for myself in Launchpad so if you want to use it on 17.10 with the normal PPA/testing warning, I also have it built for 17.04 if anyone wants that as well. I’m also running the new Qt music player Babe-Qt.
I also have the Uptime widget and a launcher widget in the Latte Dock as it can hold widgets just like a normal panel. Oh and the wallpaper is from awesome game Firewatch (it’s on Linux!)
