Ability to change document background colour (white -> black)

[jamesclarke]

I understand it’s impossible to change the colour of the background in Designer for iPad. This is a much needed feature for anyone trying to build prototypes as the artboards for say an iPhone app need to stand out against the background. The background of the artboard in my current project needs to be the same as your chosen document colour, which means I can’t distinguish the boundaries of my artboards. Currently, in order to get around this I’m placing a dummy artboard with a black rectangle behind the other artboards, which is far from optimal.  Unless I’m missing something which already exists, please consider adding this to the settings as this product is otherwise incredible. Many thanks.
