I love your effort here, and have been meaning to ask...are you working on some means to parse old-school TXT tabs from other tab sites into your format? I always thought that would be a really interesting problem to solve, especially trying to detect alternate tunings and tempos and such. You would probably need a human to come in to do a polish pass afterwards most of the time, but still might be a net win.

Hey, thanks! We'll likely eventually do that, but it's low on the priority list. There are some more structured formats (e.g., Guitar Pro) that we're doing first.
