It's always difficult to decide on a designs features. There are so many possibilities and sometimes it can be hard to tell how long something is going to take. This is especially true for software. I do have a list of features jotted down on some scratch paper, so it can be a good place to start.

Anyway, the schematic is complete. I use P-cad 2006 for schematic capture and PCB layout. Most of the newer schematic capture programs (altium, ki-cad, etc.) have many more features, but P-cad works for simple board layouts.
