I used this extension on a personal blog site, and I'd say I'm an intermediate-level Joomla! user. This extension is very versatile and can be employed to do lots of different things. The author has an awesome selection of well-documented examples which are incredibly useful, and give lots of ideas for how to get the best out of the extension. I turned up a fairly obscure bug relating to the editor I was using, and the author investigated the bug, fixed it and sent me a personal response within 24 hours. Very pleased to recommend this extension.
