I immediately created my own theme and was able to extract custom plugins out of my previous configuration. One of them might even end up in a pull request. 🙂 I used the custom plugins mechanism to split up and spread my configurations across all of my machines. So now I have a consistent set of configurations and I can activate them individually according to each machine’s purpose (i.e. no need for KDE specific settings on a server 😉 ).
A nice productivity and consistency boost. 😀
