No update so far but I have a workaround that might help. If you’re using chrome get the imagus extension. It will automatically zoom the opened image to fill the window when you hover over it. “E” and “R” rotate the image and if you need more zoom just hit “Z” and then +/- will zoom you in and out. Its not elegant to have to add a 3rd party solution but its all I’ve been able to come up with.
