Stay away

Read the other 1 star reviews. This happens more and more it seems. A plug-in gets really good, then suddenly the next update removes all the free functionality of the plug-in to force the users to pay to continue.

The developers count on the current users to pay up since the other choice is spending a lot of time finding another plug-in and getting it to work correctly.

Another trick the developers use is to not allow anyone to access previous versions.
