First, I posted my 101 sketches I made with Krita since I started working on it. I made a google+ album out of it, because I didn’t think this server could hanle 101 sketches easily. (Update: google+ died, so now they’re here.)
I actually made it 2.5 years ago, but I never formally open sourced it, more forgot about it, actually. When at the Krita sprint, Boudewijn remarked he really disliked the way how webcomics present themselves, I remembered it again and show it to him and Timothée Giet. Timothée, as a comics creator was interested in using it, and I finally took the step to open source it.
It has quite a few features, so check out the readme at github.
