As an engineer on SlimFAQ: That's exactly why we build it!

Custom domain name support is coming, per-FAQ analytics is also in the pipeline. As for a template system: we've played around with some ideas but couldn't agree on a simple and nice integration yet - but we are planning to offer more customisation options to make it easier to fit your site's or application's style.

We are already providing a nifty WYSIWYG editor - you should give it a try! Thanks.
