Looking great! Any thoughts about adding a unit conversion panel? The old Palm OS (trio, cleo, etc) had a great conversion section where you could enter something like 10 [m2][ft2] and it would pop out with the conversion. It had several categories such as volume, weight, distance, etc. Most of the converters I've seen on the market are pretty poorly implemented; you have to spend all this time picking out your units on dials, rather than buttons.
