Jxtended Catalog is the only directory extension robust enough to handle what we needed. Although we downloaded the beta version for 1.5.6 and there have been some bugs, Andrew Eddie has been super at support especially for someone like me who knows enough to get in trouble but not get out of it. Coolest features include multiple directory listing assignments and global parameter settings. Also the robustness of the navigation of the directory structure is really wonderful for the front end. We only look forward to the enhancements that are sure to come.
