I use two different hard drive enclosures a Sonnet Box and a Weibetech box which means I often have several drives attached. I plug the drives into different bays all the time and lose track of which drive in each bay.
The feature i would love to see would be a 3D map and layout of my drives and which bay they are in. If I could see at a glance that X drive is in the 3rd bay of my sonnet box then I would be very happy.
I would love to be able to layout the configuration as it is on my desk. ie put the weibetech to the left of an icon representing my computer & monitor and the Sonnet box to the left of the that all viewed form a high and 3 dimensional perspective.
that's it, I think it would be a very popular use.
