Someone else probably already requested this but I really miss a Zoom tool while editing. Like Photoshops Zoom tool where you can alt click to zoom out and click to zoom in on your document. It could also work as Sketch's 'Hold Z down to Zoom' and 'Hold Alt+Z down to Zoom out'.
Like Photoshop, if you hold down the spacebar, and then press command you will get a zoom-in tool, and option will zoom-out.
Or pinch to zoom. Should work with a trackpad and a Wacom cintiq
