expand only trees with active connections/nodes

hi,

could you add an option to only expand active trees?

e.g.
session list
sessions
group1
group1node1
group1node2
group2
group2node1
group2node2

when opening the session "group1node2" from the systray the session list will be shown as follows:
sessions
group1 -> expanded folder/group
group1node1
group1node2 -> active connection
group2 -> collapsed folder/group

then closing the session/connection and minimizing RDM to the systray ...
opening the session "group2node1" from the systray the session list will be shown as follows:
sessions
group1 -> expanded folder/group due to last active connection
group1node1
group1node2
group2 -> expanded folder/group
group2node1 -> active connection
group2node2

with the requested option set i would expect the session list to be shown as follows
sessions
group1 -> collapsed folder/group due to no current active connection
group2 -> expanded folder/group
group2node1 -> active connection
group2node2

please let me know your thoughts.
