A Clear Background

Hello all,

First time user of Discovery but long time user of Solidworks and such.  I just became a huge fan of this software, one because it was developed by a solid company and two well it's epically better then Gaussview and other modeling programs.  Anyways, I was wondering if it is possible to have a clear background when I save an image of a molecule?  It seems kind of silly but it would be quite useful.
