So I keep seeing the occasional thread pop up about reptile software. And I want to get some feed back on this. What features do you seek in these programs, and what are some popular choices? I'm a programmer, and the thought that people pay money for these things when they can be provided for free intrigues me. So I'm asking for serious feedback, what key features do you use these programs for, and what would you like to see in them? I'd like to take a shot at developing something people can use easily as part of their lives for tracking stats about their reptiles.

Submit as much info as you'd like, even including examples, screenshots, or even mock ups of how you'd like to see a program laid out for you. All feedback is appreciated!
