Coder's review: does exactly what I want and is free (go figure)

Having spent some time with my head in the code looking at how to hack SWPM to meet my requirements, I am now even more impressed than before.

The code is clear and consistent and well organized, enabling me to add extra fields or use unused database columns without breaking everything.

This is really a top quality product, and I would happily pay for it if I had to. (In fact I already tried, but there’s no Donate button at present.)
