Yummy rocks!  I'd suggest the following... Allow the queue to expand subfolders.  Currently, the queue only lets you see one level deep.  Often times, I upload complex file structures, but with Yummy, in the queue it only allows one level of expansion to see where it's at.  But that's not a showstopper by any means, but it would be nice to have.  So far that's the only addition I can see!  Keep up the great work JD!
