Once again, thanks for all the comments. I'm glad a lot of you find this useful.
This is really cool, if you're okay with it I'll use it in my game
Go right ahead, that's what it's there for.

Additions/Fixes/Changes
ADDITION - Two new conditions, "On Grid Scroll Start" and "On Grid Scroll End". The first condition triggers when the camera first starts scrolling into a new area, and the second condition triggers when the scroll into a new area ends.
FIX - Going off the top of the screen into a new grid area jumped instantly to the new area.
If this can be fixed, or maybe add an event that checks when the action of grid camera movement is occuring, it may help for example add an action of ignore user input at that moment and that will make it look much better.
Unfortunately, fixing that would be out of my control, but as you can see, I added two new actions like you suggested that will tell you when a scroll to a new area starts and when it ends. The "GridScrolling" CAP shows these two actions in action.
As usual, be sure to report all bugs and possible feature requests you have. Enjoy!
