I have a vague memory that in some previous version, when a
mailbox went offline and the Sources list was hidden, the word
"Sources" turned red, to indicate that some mailboxes were not
functioning properly. If so, this stopped working at some
point.
If my memory is wrong, is there a way to indicate that some
mailbox has gone offline? If the sources are not expanded, it could
be months before discovering an issue (as it was for me). Could be
simple, like "*" next to the word "Sources".
Of course, some users may purposely take mailboxes offline, but
I think adding an indicator would be useful for them as well, since
it would show that the mailboxes remained offline.
