Error messages missing

In the old version messages were displayed beneath the concerned folder in folder overview, i.e. no connection, account problems etc.
Where are these messages to find now?

There were not only error messages, also feedback like “last refresh 5 minutes ago”.
(not the exact words, I do not remember them even in German).

If you check mails i.e. you cannot say, was there no mail, or is there a bad network connection.
