I've had quite a few positive comments, and also, some folks have pointed out bugs and made suggestions for improvements.
So, I fixed the bugs (all that I know of anyway), added most of the suggested features, and added a couple new features of my own.
Above is a YouTube Video that shows most of the features, and how I narrowed down the reason for my crash.
Here's the latest software:

In the following YouTube video, you can see the crash, as I had my GoPro on the copter:
Works fine, very useful.
Thank you.

Cool, now it's a lot easier to others to examine their log files too. Well needed software. Yes really useful.

Comment by Rigel on July 23, 2012 at 12:30am Too bad about the crash, but great way of analyzing what happened. Thanks for sharing your work.

Very nice! Seems like great tool! I am sure it will help many of us debug things much more effectively
Thanks!
Great tool!
More users will look at logs now.
Comment by Aaron Curtis on July 23, 2012 at 5:49am Hi Dan, great work!!
Do you have any plans to integrate video (from or of the UAV) into the software? It would be fantastic if you could sync up a video file with the logs and display the correct frames along with your visualizations.
I've been working on a python script to overlay animated log graphs on video, but it's slow and adding video to your program would be a way better solution I think.
Great that you released the source! Any plans to put it in version control and on Google Code or similar?

Do You know if it work for planes too?
I´m thinking to bring back the old logs and analyze them.

Very impressive, excellent work Dan!
