Since adopting it, I’ve also grown fond of Mike, the plugin which lets users see the various different versions of a doc (without needing to resort to git).
But I’ve also experienced plenty of pain points when pushing the customisation envelop. Weird bugs appeared in many places which were clearly due to MKDocs’s poor architecture and performance was also never stellar.
Congratulations on launching Zeniscal and I’m quite excited to see the future of it, but I do very much hope that in 12 months time, one way or the other, I’m able to still have similar functionality to what the plugins provide.
