Not getting lost between SSL, Rack, Sequencer & devices would be good
In Record, selecting a channel in the SSL should do the same thing that selecting a track in the sequencer does.. move the rack navigator to the device, highlight it and also do the same effect on the sequencer.
In Reason, double-clicking on the channel name in a 14:2 or 6:2 should jump the rack to that device and animate the same highlight used in Record.
Also, tracing a signal back through devices is tedious at times and it doesn't need to be that way. There are incredibly easy and intuitive methods for assisting the user in doing this. The current cascading text menus are basically a data dump and not pleasant to use at least for a trace-back. Showing something graphic based focusing on the direct signal path (with a secondary option to redirect using the current text-based menus) would be better.
