Explain the problem as you see it
Side panels are painful to use if used often to peek at a node's content. They are not smooth in opening (often with the width different than expected) and hard to close (aiming for small "x" at the right top, least used corner), making the work with them slow.
Why is this a problem for you?
Panels are slow to use and require a lot of fiddling even if needed to be used for one action, like changing supertag settings.
