Just a suggestion that I feel would make life significantly easier for many people... the ability to upload folders via the web interface.  

I know one can upload folders using the desktop program, and that works great.  But it would be nice to be able to upload folders remotely as well.   

Say I downloaded a few albums at work and want to be able to access them at home... the albums are already contained in nice folders so it would be easy to just say "transfer this folder" instead I have to create a new folder for each album and then transfer all the files into those new folders (at least I know how to transfer multiple files at once).

Just a thought.  

Thanks.
