Well nothing ... only just a hover to much?
No there is really an annoying issue in this behaviour. Imagine the following situation on a host.
vhost-project
vhost-projectdev
Within vhost-project and vhost-projectdev is nearly the same file and folder structure ... because the dev environment is for testing or demonstration purposes.
So every vhost has/ is it's own user, but they have the same host - let's say domain.com
vhost-project ->
http://www.domain.com
vhost-projectdev -> dev.domain.com
So what's the end of the story? You have two (S)FTP entries "domain.com" and "domain.com (dev)", but when you are connected to one of them, how do you determine with which user / vhost you are connected? See the problem

?
(vhost-project) ->
ftp://domain.com/test
(vhost-projectdev) ->
ftp://domain.com/test
No difference at the statusbar on hovering the sidebar.
PS: yes, I know I could write
http://www.domain.com or dev.domain.com in the host field of the (S)FTP settings, BUT sometimes servers have a different internal host name instead of the public domain name
