Pony request: change the size of the canvas. On my 13" MBP at 1280x800, there are highly-fucking-irritating scrollbars for the canvas. This fucks me up a lot. I'd love to be able to resize the canvas or "zoom out" so this didn't happen. I don't actually need 960px to play with to design for a 960px wide site.
Give me this tiny horse and I'll abandon Balsamiq. Thanks!
I came to request similarly, then noticed that if you make your browser window big enough, you'll find there's a green canvas resize grabber in the bottom right of the canvas (when you hover over the canvas). This is great, but definitely easy to miss when the canvas starts out so large.
You can resize by dragging the handles at the bottom, right, and bottom-right edges. You can also use the chrome/safari full page zoom option to zoom out, the application keeps working fine (though there are a few slight rendering errors).
You can actually resize the canvas. Just move the mouse to the edge and a resize tab appears. You can drag that to shrink it or input values into the text fields - https://gomockingbird.com/help/Editing/#resize_page. Hope that solves the issue at least part of the way (zoom would be nice though).
