I like this Add-On allot! What would be really cool is if one could choose to set all mails from *all* accounts to "read", not just the active one. Use case: I have an IMAP mail account on which mails are deleted after 45 days. So I copy all mails by a filter automatically from there into a local mailbox, on which I normally read my mails (here, they aren't deleted). When I now click on "Mark all read", it would be cool if all mails in all folders of my remote IMAP-account would be set to "read", too - although my local mailbox is active.

I'm currently on Thunderbird 17.07 and the 'mark all read' button conveniently does exactly what it's designed for, marks all the emails in the active folder all read. thanks 001101.
