You fellas don't know how thankful I am of all your work. As a student I can say it's been rather revolutionary to experiment with what you've come up with. It allows me to learn very complicated structures of ideas in a nice and tidy way as I can see everything logically organized at the front of me. Also I am able to recall things by revisualizing them back in my mind when needed, so my memory has got one more 'recall level' to hang on to.
Should I be able to remember you fellas/this project in a monetary way in the future, the opportunity will not be ignored. I love the software and I know it helps lots of other people too.
Still, there's a lot to do. I hope you fellas got the energy/resources to keep up the pace. I'm thanking you from the bottom of my heart. Cheers! :)
