Have given emClient a try after years on AppleMail. Whilst emClient has many of the features Apple Mail does not have, it does not have one absolutely critical feature that is a deal breaker for me:
I work with many folders and filters (customers, suppliers etc.) and there are parent folders e.g. customers and suppliers. You cannot keep all the folders list expanded as that takes too much of space and scrolling, hence I collapse the lists. And here’s the problem: in Apple Mail even if the list is collapsed, you see if the new e-mail has arrived into any(!) of the subfolders (e.g. within “Customer” parent folder) as Apple Mail displays the unread count for the parent folders.
That is super comfy feature and you do not have to expand the categories numerous times just to check if there are any new messages - that’s quite crazy. Given a great feature of emClient to display then new messages, it’d be just awesome to implement this parent folder unread count + new messages - it would be a life saver.
Two more things that are quite annoying:
You cannot bring the list of the emails thread to be sorted to display new message on top, it’s always on the bottom albeit in the e-mails list you can configure this so it’s quite counter-intuitive.
Please fix the unread count and that would make the client just awesome!
