I was tinkering around this evening and noticed (how I missed it before I’ll never know) that both editors can be re-sized. I also noticed that both can be resized outside of the SP containers limits – i.e., you can resize the editor windows larger than the area SP resides in which blows the SP container out of whack. This could cause some issues as when I resized them I was able to resize to a point that the resize hotspot was not in a viewable location. In my cause it was under the sidebar, but I expect it could be resized completely off screen. Luckily I noticed before I released the mouse button.

Probably not a big issue, but this could cause issues with less savy users.
