It might be a little too much to expect, but it would be nice if there were an option to change the meaning of the little red numbers that show up on the Mail icon, the Messages icon (and other messaging apps) from “unseen” to “not replied”.
I often quickly visit a message to see if it’s something that needs dealing with straight away, and go away if it is not that important. But as soon as I do, I lose the little number that reminds me there’s a message to deal with. The whole concept of changing an icon with a little number to show how many messages there are is brilliant.
And undoubtedly for many more organised people knowing how many new messages there are is just what they need. But some of us would like to know how many messages have not been replied to or dealt with in some other way.
