stopwatch features on calculators

[pier4r]

I have to say that after having (re)discovered multistopwatch and dived in to it a bit more (DavidM quality! impressive), one of my hp50g has little rest since a couple of weeks weeks. I am using it to get a trend how much time I use for some routine tasks, to try to plan better the day/week.

Yes I know I could be efficient, start the timer, then quit the program, then enter the program and stop the timer, but that's overhead that sometimes is not in my mind so the 50g mostly runs adding fractions of a seconds without pauses.
