I may enforce other limitations at some point if I feel there needs to be more incentive for people to go to the paid version, but for now, it has all the same capabilities as the paid version.

Mike, the limitation to a total of eight charts, alone, is enough to ensure that those who need MSPro (99.9% of all potential users) will go for it.  Anyone only using eight charts would be just as happy to stay on paper  .
