See through character camera while editing level

Hi all,

So I am working on a sidescroller 2.5D platformer. I have a character and a camera banded to him. And camera is changing all the time it’s position (relatively character) and parameters, depending on position in level.
And it is important to place props depending camera position to create beautiful composition of foreground and background.

So is it possible to see through character camera while I in process of level editing?
And is it possible to make camera act like in game (moving and changing parameters) while I simple move actor in editor?
