It would show like this:

- TOnlineState.SwitchStateToOffline( Connection: TBaseConnection)
  + Connection.SayGoodBye
  + Connection.GoOffline

and then when I click on one of them It would scan the whole project and
then pop up a list of all possible overrides that looks like:

 TBaseConnection.SayGoodBye
 TFooConnection.SayGoodBye
 TBarConnection.SayGoodBye
 TFooBarConnection.SayGoodBye

and because I know that I am interested in what it does with a
TFooBarConnection (because somehow I know (from understanding the code)
that I *now* want to know what will happen with a TFooBarConnection) I
click on TFooBarConnection and then my Tree looks something like this:

- TOnlineState.SwitchStateToOffline( Connection: TBaseConnection)
  - TFooBarConnection(Connection).SayGoodBye
    + MySocket.Send('quit' + #13)
    + SomethingElse.DoSomething()
  + Connection.GoOffline


Later I might click on it again, delete the subtree and explore a new
one with a different override.
