Testing a theme during its implementation

Hallo, I would like to start creating a theme. I was wondering how I can see the theme “in action” without installing it on the Live Hub TV. I mean, is there a quick way to make changes in a skin and to view them, in an application like a broser ? THanks

This is possible? I mean, running the theme without using the WD TV Hub?

There is No Theme Simulator or Emulator, nor plans for WD to create one. (see here)
