It would be so cool if the site kept track of one's workout/practice history. From there one could look back and see what tutorial(s) they accessed on any given day instead of having to notate it individually on a external source (i.e. keeping a handwritten notebook of the tutorials done on a certain day). I know there are workout sites that have this feature; Nike training, for instance, keeps your 'history' -- even the free version. Any chance for something like that in the future to help students track their progress? Thank you. This is great stuff, and I recommend it to any student at any level. Happy dancing!
