I installed McPhling which gives me a quick way to flip between apps. I also installed CrossingOver which lets you do caps by writing graffiti on the line between the letters and numbers. From what I gatther, this was a popular hack with pre-PalmOS 5.0. Then I installed Graffiti Anywhere which allows me to graffiti on the screen, including the crossing over functionality. Finally, as my intro screen when I turn on my Palm, I installed Today which gives a nice summary of whats going on.
