I just upgrade from PI 07 rev 1 to PI07 rev 4
Lots of neat new features like a today plugin and an awesome profiling/scheduling function via categories (you can limit by category what shows up on your calendar at what time-meaning on the weekend you won't see work items or during the work day you won't see your spouse's appointments)

I have a couple q's if anyone can help.

Where is the folder for color schemes now? I can't figure out where to put all the color schemes I made so I can choose them along with PI's built in ones.

If you haven't done this upgrade do it. It's very cool and the scheduling function alone is worthwhile.
