Show server tags in side bar

I am currently testing emClient to figure out if we can use it in the company.
It all works well but there is one thing that is stopping us from using it:
One of our e-mail addresses is used by several users and we work a lot with tags.
It seems it is not possible to show remote (server) tags in the sidebar (left).
In the ios app you can only filter by local tags, let alone set a remote tag.
That might be ok for a free POP3 mail account that just one person uses but in a business enviroment with Microsoft Exchange synchronisation should work flawlessly.
Is there any chance to implement this feature in a future update?

It would also be nice to see the number of unread mails next to the tag name in the sidebar.
