I have to say this has to be the fastest knowledge base out there. Besides speed, there are lots of features that are amazing, like custom CSS, password protection, your own branding,..
The only thing I would change is the article text editor, I did find some problems using it. It would be nice to have a CKEditor or notion style editor. I am also looking forward to the multilingual features and CSV articles import. Eniston is definitely a gem if you are looking for a great knowledge base!
