Dynamic Resizing

Does the Composer GUI support dynamic resizing (IE: display.newImageRect() )? I’m putting my @2x assets in as normal but it doesn’t seem to utilize them at all.

I also can’t seem to figure out how to make it universal for tablets and phones. When I run the simulator and switch between devices it’s not consistent, and on tablets most of the assets are completely off screen.

I’m using the modernized config file with the 800 x 1200 numbers.
