I would like a similar experience in the browser that we have with the mobile app. Set an expiration where the user can still unlock quickly with PIN.

A trusted computer browser stores the main logon cookie with no expiration. But this cookie only has an encrypted blob that cannot access the mailbox alone. The 2nd cookie set to expire in X minutes/hours must be combined with a user supplied PIN, and that will decrypt the non-expiring main cookie blob, which logs the user back into the mailbox.

The Lightning Network is in beta, but it allows for instant payments (no confirmations) and almost 0% fees, provided the user has a channel open. You already accept Bitcoin... and the Lightning Network is a major upgrade to way people will use BTC to make payments. If you do it soon, you will also get a P.R. boost, as it will inevitably be mentioned in the Bitcoin media.

It would be great to support SMTP/IMAP with a dedicated and a very low fee plan.

Or maybe with a one-time fee, only for this feature.

It would be great if each user could modify the default level required in SpamAssassin (4) to another value (e.g. 5 if too many legitimate mails land in the spam folder).

As long as my other idea (https://protonmail.uservoice.com/forums/284483-feedback/suggestions/34132327-spamassassin-set-required-level-for-each-user-sep) is not yet implemented:
Set required level in SpamAssassin more conservatively as suggested by SpamAssassin:
https://spamassassin.apache.org/full/3.1.x/doc/Mail_SpamAssassin_Conf.html#user_preferences
Default (for single-user setup) is 5 - for ISPs they suggest that "you should probably set the default to be more conservative, like 8.0 or 10.0". ProtonMail sets the value to 4 for all users! That is too low!

I like that I can edit the CSS, but it takes a lot of work.

There seems to have been a selection of themes in v1, and on https://protonmail.com/blog/protonmail-themes you write "stay tuned for updates regarding themes in ProtonMail 3.0."

I found https://amdelamar.com/pm-theme, which should work with v3 (haven't tried them myself), and Detchem from here https://github.com/scastiel/pm-inbox-theme still mainly works, but the CSS is too long for the few things I want to change.

Please make working with themes / CSS easier and/or add a place where people can post their CSS and screenshots of how the result looks.

i for got my password and recovery email what to do

It'd be great if we could go into our settings and pick "fullscreen" or "small" as our preferred way to display the composer window.

I want to place the ProtonMail Signature within my customized Signature so that it is not always my signature followed by a blank line followed by the ProtonMail Signature. The blank line does not fit with the formatting of the rest of my e-mail's text.

Removal of ProtonMail adverts on 'home page' - for paid members using ProtonMail for business, we aren't keen on all our staff seeing the ProtonMail adverts when logging in i.e. ProtonMail is the highest rated app, also, the ProtonMail shop is now open....etc etc

This looks a little unprofessional, and we would ideally like the option to remove it for our paid accounts. Thanks.

Right now, in the app, when one wants to move an email from one folder to another they can, expect for the inbox. There are times I’ve swiped the wrong way and my email goes to trash. I want to put it back in my inbox but cannot on the mobile app, only on the computer site where it is an option. It would be great if you could add that availability in the mobile app as well, which would be a very simple fix on your end.

Could you authorize to include a bit more contacts when sending an e-mail? I'm sending press releases from time to time and 25 isn't enough... Something like 50 or 75 would be much better so I wouldn't have to write 3 messages or so. And I can assure you I'm not spamming anyone in doing so.

Thank you very much!

ProtonMail Bridge has bugs integrating with the Mailspring email client. The Mailspring team have expressed interest in working together to get these issues resolved. If the bugs could be fixed and the Bridge could get working with Mailspring it would be a great productivity booster!

Really self explanatory, as a pro user I have 5 email addresses on a single account and I think it would just be better if I was able to use the auto replier for each email address individually instead of having a global auto replier for every address on my account. I wanted to do this today and couldn't believe this wasn't possible already so here is my suggestion.
