If I’m missing something, please correct me, but I don’t see a Mark Read or Mark Unread button or icon in Runbox 7. Mark Read/Unread also needs to be front-and-center, as in Runbox 6, with no extra clicks (drilling down a menu tree) to get to it. I also need to be able to apply the setting, as in 6, to multiple messages simultaneously.
Overall I think Runbox 7 has many worthwhile new features, but if we’re losing this feature from Runbox 6, I can’t use Runbox 7, period. It’s that critical to the way I work with email. Especially at this holiday-shopping time of year when I get multiple emails daily from a number of merchants announcing (and repeating announcements of) various promotions, I need to be able to quickly scan through email headers and determine which few messages are worth my time to open today. I don’t want to unsubscribe from or autodelete these messages, because a few have an earned rewards code or are otherwise worthwhile. I also need to be able to see at a glance an accurate count of messages I still need to process in some way, so just filtering them into another folder (which I already do anyway) doesn’t satisfy this need.
There are also times when I read a message, don’t have time to deal with it immediately, but need to remark it Unread so I remember to deal with it later.
