I agree. I'd like to see a portable hand replayer (not web based, not PT). Something that would allow me to throw several hand histories for a tournament or for a ring game session then step through and pause at each decision I had to make. The abililty for me to add notes to different streets and save/export hands for more analysis later would also be useful.

I'm near the point myself where I'm just going to pay someone to develop this for me because I can't code in anything that makes a decent GUI.

The hand range program is interesting and something I've thought about myself. The ability to backtrack through PT and find previous similar situations is interesting. If you do choose this approach, I'd definitely recommend reading through the University of Alberta's research into opponent modeling if you haven't already.
