Recently I have been thinking about pushing one of microchip's very cheap microcontrollers to the extremes through using a lot of IO multiplexing without the aid of discrete logic ICs. I am at the stage where the schematic is done, and I have built a working prototype a long with some software.
Problem for me is that, I don't know what would be the best features to implement / compromise on. I only have 2KB of program space and I am using C to write the software.
What I initially had in mind was:
Can anyone think of some other / better features to implement?

What I initially had in mind was:
- Manual general purpose up / down counter (see how many times the door of a shop opens each day to evalute business)
- Programmable automatic count up / down timer with 1mS resolution (switch on something when the count reaches zero)
- Lap timer / stopwatch ...
Can anyone think of some other / better features to implement?
