First let me say that this is very cool stuff!!!
I am amazed at what members will do of their own volition. I love it and I respect the time and effort placed in building it.
Second, let me say that I am a programmer and software engineer myself as well as the EQP for my ward. I do not say that to boast for either. It just helps to explain my perpetual curse of feeling like I can contribute.
That being said, I think that I have a few embellishments I would make on the screen shots that I see and you ca decide what if anything you want to do with them.
Sorry it's big...here are my thoughts:
Details column would be a link to more details.
As an EQP, I would not only like to know if a family was visited, but when (Is it all being done at the end of the month?) also what kind of visit (Did they just call?, Write? Show up?)
I would also like to know whether or not a lesson was given or the family has needs.
I have eliminated the notes box from your screen shot to avoid getting information saved that is confidential and replaced it with a simple checkbox requesting a PPI.
I know that a lot of this is California Dreamin' (I'm in NorCal) but I usually ask my hometeachers those questions anyway...those are my thought right now.
On a side note...are you making this available to anyone to run locally for fun? It doesn't hurt to ask...
