I did some enhancements to DisplayTag. You can start by reading my previous post on DisplayTag.
There were some features that I needed and Displaytag didn't have them. I took the source code and I did it.
The enchancements are not in Displaytag trunk, you will have to take my build or add it your self to the trunk.
I didn't see recent activities on DisplayTag, but I would like to see them...
