I don't think what I'm requesting is very standard, but in my book it would be very useful. Let me explain it.
I don't really like the "auto-hide" feature that hide a panel when you stop using it, because things never seem to happen when I want it.
So I end resizing my Build window a lot, to small when I mostly edit size, to big when I'm looking at some output.
May I suggest adding in a feature where some double-click or press of a button would alternate between 2 stored sizes for the panel (kind of like window manage have a full-screen and a custom-size size switch for windows).
Else, what kind of solution are you guys using to solve this, or is this a non-problem to you?
