Not a particularly new idea, but long overdue for re-considering. Competitors have been doing it for a decade, but when sending a Dropbox Transfer link in an email to multiple recipients, it is impossible to tell who has downloaded it, just a number of downloads, which can sometimes even be the same person on multiple devices.
Please can the notifications identify the "downloader", and, ideally, the download page too?
Ironically, and rather uselessly, the only time I have received a Dropbox email notification that says who the person who downloaded it was when I did a test download myself, and it put my name in the text of the email, so it must be possible at some level.
