does this work in firefox? I started changing values and nothing changed on the left panel.
It does work in firefox! You need to manually enter things instead of using color pickers though.
For example, if you go Components -> Jumbotron -> Background Color and Paste in #000.
It should update the Jumbotron background color (you will have to scroll up perhaps to see it).
Does that work for you ... or if not I will need to look into it, as it may be a bug :(
