At the moment, it takes a lot of clicks to add a file. Most are unecessary, and having added over 1000 files to my courses, I have NEVER gone to the filestore to find an existing file. I have always followed this route:

open filestore -> click upload -> click browse -> choose file -> click upload -> find file (what order are they in?) -> click choose

This could be reduced by having the browse button next to the choose a file button. Then, when I choose the file and its address on my local machine is entered in the input box, the page can automatically add it to the filestore when I press submit as well as creating the resource.

I've marked this as major, because the frustration and wasted time this causes is significant, especially for new users.
