The ability to post notes and markings on one graph layout without it appearing on all graphs, or at least the ability to toggle the notes on and off. Graphs can get very cluttered at times and it would be very useful to be able to note trading ideas and entry and exits on the corresponding stock graph without it looking (even more) like a road map. I would use it as a quick and easy trading journal as,I think, would many others. I think this would be a winner.
