Till iTest 4.2.0, there was not much we could have done with topology views in iTest. Like we were not able to select any specific position / point for any link on the device and we were not able to relocate the link if required.
With iTest 4.2.1 release, the topology view has been modified. Now we can place the links between the two devices at our desired point / position on a device. We can relocate the links at any point of time as per our requirement and we can give any shape to a link to find the connections clearly (if there are many connections).
