Gmail has a feature that allows me to read my emails without them being marked read unless I click the envelope to mark them read.

This allows me to read emails I don't want to reply to yet or that I haven't dealt with yet and they remain unread and visible in my Inbox. Once complete, I can mark the email as read and it disappears from my Unread Inbox.

This also ties into the many requests to have a separate Unread Inbox section (not just a filter). Currently, I have my Inbox so that I only see Unread Emails and not everything. I can see ProtonMail has a filter but anytime you refresh the Inbox, you get everything and have to filter the Unread.

I really want to switch to ProtonMail but without these critical features, I have to stay with Gmail. :(

Thanks kindly.
