I've been using SQLite on several minor projects now (it makes File IO so easy), and the one suggestion I would make would be to make the documentation (api reference) downloadable. It would be very handy for myself and probably many others to be able to download the API reference and keep it with our projects. For me at least, I'm a high school student and work with an IDE running from a flash drive in the Computer Science lab, where there is no internet, and documentation would be so much better than digging though sqlite.h
Thanks, Andrew
