I found it usefull on version 2.3 when i organized the computers by port.
Cause the servers are configurated to RD connection while the workstations are configured to VNC connection. 
Now on version 2.5 i can not do it anymore (cause there is now 2 collumns to display the ports) wich creates a handicap for us
. Since i can not use anymore this tecnique. 
So here goes the suggestion: would then be usefull to the icon before the connection name being a collumn on its own. This way can again sort the computers by type of connection. Would thank some kind of reply from the staff to know if this is something i can expect in the future. 
Thank you in advance for any replies.
Tiago.
