Hi Gang,
The simplest is to right-click on the server connection and the click on Properties. This can be done from Perspective.
The other thing you can do is to name the connection based on user. When naming the connection, add the user as part of the name.
See below.
When connected it will show user@server. You can setup multiple connections to same host with different user names.
Thank you,
