I think a way to make this happen would be to give GMs the ability to change which character they are signing in with. Basically, on the top left, where it lists your character name
Example From This Page:
LonePaladin : User Preferences
It would replace the name with a drop-down. Anyone with multiple characters (which automatically includes the GM) would be able to select one from the list, and have the page show only that character's options.
For the GM, this could also let them see how a post appears to a character, with hidden elements actually hiding. (This would let them double-check to make sure secret bits don't leak.)
