I would like to see a "mirror" view of the PCB as an option. Basically a rear view of PCB with all the "highlighting" options still available. I like to hand wire a board before sending it off for production and it would be handy if there was a mirrored view of the PCB that would show the various nets highlighted as the normal view currently does. It would enhance the building of a prototype board before the final production. These boards are typically thru hole versions to test the circuit.
Brand new interactions and interfaces. 
Easy to use and quick to get started.
