I like #Tutanota (@Tutanota) a lot, but 3 main problems: not being able to use other mail clients. Not being able to search easily in your mails. Not being able to send encrypted mails (using PGP keys for example) to people who don't have Tutanota, in my case, all my contacts.
If the last two problems were solved, there would be no need to be able to use another client, which we cannot do anyway at the moment.
@Tutanota And no, I'm not going to give a different password to each person, it's annoying, non-intuitive for these people, and there's often no way to get the password to them by any other means + the day Tutanota's servers don't work or Tutanota simply disappears, access to these mails is lost
