Receive-only version

[CubeOfCheese]

Is your feature request related to a problem? Please describe.

I would like to use this in my computer class to send files and urls to my students. However, I do not want them to be able to send files easily to each other. So if I could install a receive-only version on all the computers in the lab, then I could easily send them things during class.

Describe the solution you'd like

Another version available to download that is able to receive, but not able to send anything.

Describe alternatives you've considered

I tried using the share as link, which is cool. However, trying to share a simple url is clunky because it downloads a text file instead of allowing to copy and paste directly or opening the url directly.

Additional context

I would also be content if the share via link UX was improved so that it displays a text box in the browser for the user to copy and paste from. And having an open button like the app has would be extra great.
