Nick, do you know if there's anything like that that would let us load our own tabs into it rather than select from a pre-made list? Because that would be pretty groovy.
I don't know of any program that does that. The problem is that formatting is an issue, since tab writers use their own formatting. I think it would be possible to do this if the program required a certain type of formatting.
I had this discussion with Joel form Harpsoft when he was integrating his app with us. It is a difficult thing to program. If I wasn't so busy it is something I might even consider tackling.
