Somehow I got these turned on and don't remember how to hide them.
 

 
Can someone remind me as to how to hide these?

See the tip for Week 17 in Friday's Tip of the Week, it covers what these are and why maybe you want to use them from time to time rather than hide them.

Hi. I just plowed through Craig's tips to find it, and was beaten by the man himself

All the best.

Actually I think this is the link you want...but Zargg's link goes to something useful as well 

Thanks for the reminder. I can see how they would be useful.
 
A few other things that I'm curious about that is somewhat related...
 
Is there a way to scroll through those settings? For example, the BlueVerb effect has many more settings than are shown in the window but appear to be unreachable from there.
 
Also, what is the difference or advantage of the pro channel effects from the standard insertable effects? The recent release of the CA-2A leveler (thanks for that!) shows as an FX insert and also as a pro channel insert? Other than the additional gui in the pro channel section, is it better for it to be inserted in one place over the other?
