Woha! That's some serious design there. I am heavily, heavily impressed by what the KDE folks are building. I will admit that I don't think I'll switch to KDE anytime soon - I had been using it throughout the 3.x series, and was extremely excited about (and then disappointed by) the 4.x releases, but then switched to MacOS and never looked back.

If I get myself a workstation again (and there are solid reasons for doing so, like CUDA for DNN development when you're tired of working on servers for local development), I'll definitely give KDE another go.
