I see here that there is a way to adjust the time div on this gui, but I cant figure out how to expose the controls.

My gui looks like the first image, and has no settings exposed. Their second image shows the settings exposed, and I would like to know how they did that.
You can use the middle mouse button to expose some controlls. The last option in this drop down menu is "Control Panel", which is what you are looking for.
