I really, really like this plugin.
It's easy to use, highly configurable (but not full of bloat features you'll never use), provides nice clean output and just works really well.
It does everything I've needed so far. Be sure to read the Documentation as there's lots of options there you might not initially be aware of.
As far as future enhancements goes, it'd be nice to have some additional optional layouts for download lists (e.g. select menus, sorting, custom date formats etc.), and multi plug drag-n-drop uploads in the Admin section. But really, that'd just be icing on the cake.
