Would love for a feature to reserve an area in the Drive for a person with a link, auto-expiration, and password to "drop" files to an upper size limit in.

I don't like how people with email services outside of Proton or likewise send me things using their email without password protection or expiration.

There is no way to enforce that the file be deleted from their email. They might just plain forget or not know how to do it fully.

Sending them a link to DROP a file into my Drive will let them upload directly to a secured environment which I can then destroy the link to after the file is received.

Many people are adverse to creating a Proton account for this file submission if they are a business and need the domain, etc.
