Display message count for each folder (not only unread messages)

Currently eM Client only displays the number of unread messages (in blue) or of new unread messages (preceded by a + sign, in red). It would be very useful if, as an option, it were possible to also display for all folders the number of total messages contained. So, that, if a folder contained, say, 2 unread messages and 23 older ones, the number would be displayed as 2/23 (or, if a new message appeared +1/3/24). (Please see screenshot mock up) This should be an optional setting, so that only those who need this feature could use it -- but I, for one, would really appreciate something like this.
