Currently, only https://wp-devil.de is running on CP. Its my main blog these days, and also a text bed for my plugins, to some extend.
But I’m working on setting up my very own portfolio site with CP, and as if that wouldnt be already enough, even using Multisite, for multilingual content 
Although I’ve initially just wanted to use it, essentially, for setting up extended forms with CF 7 and the CF 7 Conditional Fields plugin, I’ve recently decided, to also properly set up my portfolio. Before, that has always been an excerpt of the most recent or remarkable projects I’ve been doing, but for some of them, I want a bit more than just a singular screen or a bit of text, e.g. the datacolor website.
