I have what are now multiple email chains dating back more than a year. These include broken series of replies to a single thread. With extremely sensitive and high risk issues it is crucial to maintain and be able to reconstruct chronologies of what was stated or claimed and by whom, when and in what order. As it is I have found very few features to keep track of email histories. Obviously Proton mail do not want to accept liability for features said to provide additional security beyond what can reasonably be offered but the software could simply add better features for searching, review and organisation.

Having separate inbox and outboxes adds friction and the emails and their replies are in separate folders. I have discovered I can move them all to one folder but then it ceases to be obvious if I have sent or received each email in it. There also seems only to be the star option to highlight a mail. How am I to tell my different starred emails apart? It would be better if I could add labels to emails. It would also be nice if I could see all my sent and received emails in one place in chronological order. Also, it would be nice if I could colour code emails with a dot and then show or hide messages with specific colo9ured dots. That way I could separate different chains and with labels I could highlight important content or inflection points in what happened.

As it is I think the system expects everybody will only want to look at and reply to the most recent emails then forget them. Over long arduous sensitive chains sometimes the past contains crucial evidence and the way it is structured now it is hard to use the emails as a database I can query and mark with notes persistent across sessions.
