[Evolution] Can evolution show the count of unseen emails?

[Jorge <jorge13515 gmail com>]

Hi.  I have IMAP access to a shared mailbox that has 51 unread emails.
I will not immediately read every old unread email; I will gradually
read some of them. But I want to notice every new email, and the
unread count is not user-friendly in this situation because I would
need to constantly monitor the unread count (which will change as I
read emails), remember the last value, and notice when it increases.
So I would like Evolution to show the number of unseen emails (emails
that have arrived since I last opened that folder), like Claws Mail
does.  Is it possible?
