Downloads/uploads units and progressbar.

It would be nice to have file size in megabytes instead of plain bytes, that's a little too much information for my brain to handle :-) Changing the width of progress bar is a cool trick but it serves no purpose. If all progress bars were aligned it would make a vertical plot, allowing a quick glance over progress of all files or dirs. If you really want to save space it could be combined with status column, it's redundant by changing the font color of whole row.
