Sometime in the past this future was removed and never returned to new dropbox implementation. But could be very useful for dropbox file selection (and reporting).Here's the case: 10 months course/training with 30 participants, each of them produces 10-20 files related to one of the platform resource. That finally gives more than 300 posts. At the end I need simple report: file name, platform bind resource, time/date of the post. I can do it, if each of the participants folows the given filename convention. But can not force them to use the convention. If there is additional meta-field for the file description, this one forces them to think again about "linking" the post with originated platform resource.
And at the end, there is the humle wish: meta field, that can be filled freely and/or from list of available course/training resource (btw, LP builder includes something similar)
