@Scott - Unfortunately, we didn't have the time to improve the front end widgets. We just extended the default download list, so that it can list files from the currently selected library plus all of its sub-libraries. The documents are displayed in a flat list tough. We'll improve this.
@Andrew - 5.x was greatly optimized in performance aspects, especially version 5.4. For example, start-up times, and working with the back-end are much better than the 3.x version. I suggest you raising a support ticket - we'll help you with checking the performance.
