Smaller Grab Window

[Korahn2610]

Hello, This is a very cool bit of coding. I was curious if there was a way to make the area around it smaller. I'm new to design work and haven't been able to figure it out on my own. I would like it to not start the animation until you are actually over the ribbon. As of right now, it starts to interact with it from quite the distance.

This is where the cursor is when the ribbon pulls from the corner. I'd like to be able to modify the area that the cursor starts to interact with the ribbon.
