Hi!
I would suggest something that sounds very well: custom URL with the username.
https: //www.dropbox.com/s / ........
There is some way the link is based on my username for example:
https: //www.dropbox.com/s/ FJR / ..........
Things of this type, could be useful for example to identify if that URL in the system is from a file that has as owner someone pre-authorized ...
Among other dozens of benefits 😄
My suggestion is to have an account option where I can choose my custom URL and decide if it applies to all my public links or only in some specific folder (thinking about privacy)
In my case I would rather that all the links I generate had my custom URL, even the links we generate with right mouse button on Windows.
PS: Custom Domain would also be incredible to have, a whitlabel for advanced Dropbox accounts.
