create a connection with default server
create a connection with specific server with same name as default server.

Now there are two identical entires in the explorer with no way to differentiate.

I suggest:

A) If you explicitly enter the default host manually (while having "Use Default Server" unchecked), then the server should not get treated as default server.

B) Properties View shows the actual url/key for verifciation/testing/info purposes.

C) the label/decoration should somehow indicate its a default server. i.e. redhat@xam.dk - openshift.redhat.com (default)
