Currently the only thing for me that definitely needs improvement is the configuration of GDM because I just can’t understand why my display configuration doesn’t get applied to my login screen so that my login is on my secondary monitor instead of my primary one. And why can’t I set a wallpaper for my login screen easily? Things like these should be built in.
Don’t know if the first time had something to do with Nvidia but I changed something in GDM settings and couldn’t login anymore, it just returned me to the login screen after typing in my password. The second time it said something about a missing kernel module upon startup. Both times I followed the same instructions you linked but doing it through the software center is definitely simpler and more straightforward.
But if you want to create another email address, you get a handful of custom ones for free with the subscription too. You can revoke these the same way, so you can have a professional looking email to hand out to people that’s not auto generated, without giving out your account’s root email address.
These addresses are not as easily revoked, you have to contact support if you want to remove them.
I wish the forwarding with email aliases would function a bit differently. Right now the alias is set as the recipient in the email and I wish you could set the recipient email to whatever email you want (like one of the additional emails you can set in Proton Mail) because the way it is now it makes my general filters useless and I would have to add even more filters.
Edit: I created a suggestions on their feedback site here: https://protonmail.uservoice.com/forums/953584-proton-pass/suggestions/48496442-show-use-forwards-to-email-as-recipient-in-forwa if anyone cares to vote for it.
I have never searched for a message ever.
