Hi Michael,

Since it sounds like it could be a while before we are able to export dimensions, is there a way to bind a background color change to a hot key. I like to work with a gray background and would like to be able to quickly change it to white for a screen shot of the dimensions, then back to gray again. I hope that makes sense.

Thanks
Terry
