does K9 have the possibility to “pin” mails? Old mails get purged from the device so that only the latest 25 (or whatever you set in the settings remain). But sometimes I would prefer if I could mark a mail as “Keep it”.
E.g. I buy an admission ticket and they send me a QR code in a mail. Not a PDF or .pkpass file that I could save, but just an email containing the QR code as an image. Bad luck has it that the mail will be purged just before the event. I can get it back by selecting “Get 25 more mails” at the bottom (possibly multiple times…), but it would be much more convenient to “pin” the message.
Is there any possibility to do something like this?
