Show HN: Refinator, online lecture notes and PDFs with prerequisite lists

I haven't worked on this in a few months, so I figured I'd just show off the current state of the project since I'm unlikely to be able to work on it in the next couple of months.

This is a _really_ simplistic proof-of-concept for something I've often wished to be able to use myself, although I should really support real books as well. Among other things, I've often felt that prerequisite and "read alongside" lists (ideally based on (topic, sophistication) pairs instead of being specific books as it currently is) would be great to have. The about page[0] goes into more detail on this.

Currently, I plan to integrate with MathOverflow/MSE's tag wikis, and maybe allow rep to transfer over in some sense from there by allowing you to link your accounts.

Any edits or additions would warm my heart. Contributions to the code[1] are welcome too! :)
