The site is lacking some basic file management capabilities. It'd be great to:
Perform batch actions, e.g. delete a select set of photos/videos/files;
Sort files by size and format (i.e. photo, video, etc); and
Automatically identify duplicate files for deletion (if you can recognise a person's face in different photos, at different points in time, with different light and colouring conditions, I'm pretty sure you can spot identical files).
