Own PGP keys
Add ability to upload own PGP key (normal or e.g. RSA 4096 or ECC).
I would concur. The ability to manage and import keys is important. Particularly for communicating with people who don't use ProtonMail.

Would love to see development on this
Greater ownership over PGP keys in general would be a great feature.
I would love this feature too, it's actually the first thing I looked for after making an account. I was disappointed to see that this doesn't already exist.
