if anyone gave this a bad review, it is becausa e they didn't get it or it was too big for them.
I made a hugely complex web app with a calendar visualization and a huge amount of data elements, and this extension handled it beautifully! it would have taken me months to code this project myself, where with Fabrik - I did it in days.. and better than I could have coded it.
Even if you need something very simple. you cant go wrong with this extension. It is on my MUST list for every site I manage. I have already turned others on to it and they are amazed.
The SNV nightly builds are great and support was awesome, I had one smal issue and within a few hours Rob had it fixed and uploaded to the SVN to update. just awesome.
Download it. You wont be sorry you did
