New DropBox Feature Might Make Grading Easier

DropBox has introduced a COMMENTS feature that lets you look at a shared file in your browser (Microsoft office docs and PDFs all seem to work) and make comments in a sidebar.  Anyone who can see the file can make comments and you can notify folks that there are comments just by mentioning them.

Potentially useful for feedback on student papers and for group work or committee work where downloading document or group editing in something like Google docs is either too intrusive or too slow a process.
