Yeah.. and if you look at my thread, you can see what everything does. I like half seconds but it goes all the way to 1/5 seconds. Not sure I'd use that, but it was easy to include. You can up the number of beeps and such as well. One of my issues with Pikatimer was the fact that the beeps are so long and trailing. Seems like you never knew exactly when to hit it. I'm a purely audible person. I can hit far better if I don't even look at the timer.
FYI, the suggested second sets it to the lowest overall time possible, I know that some people/DSs are to slow for that, so it may have to be changed a little.
