Do this yourself in the options.

No.

Why? You realise the editor is for editing, right? It's for moving everything around, and the MP screen is set up differently from SP so it needs to be accessible separately.

Better yet remove them.

Already exists but I guess no one's found it yet!

Fair suggestion, has been considered for a long time but was never a priority.

While I've thought about this, it's hard to decide exactly what part should be a freestyle section. How many seconds long must a gap be? How many seconds before/after the last/first note of a section should it start registering boos? How does the player see this intuitively and not accidentally hit a boo when they think there should be a freestyle?

Rock Band 3 style... I don't have a problem with this as I value user experience slightly over score integrity, but it does seem somewhat susceptible to abuse. Even if you rate limit it to only be usable every X seconds, it can still be used right before a particularly hard part. I would go for it though.
