Before and after Edit Feature + New Zoom

I dont know if there is a way already, but I would like to be able to turn on and off the edit on images in adobe bridge. When I have edited a photo in lightroom the Xmp file make it so that you can see the images edit in adobe bridge. This is very nice, and I like that it kind of fades in when I click the image (the edit fades in), but I haven’t found a way to turn the edit off and on again. It would be quite nice if you could add this. 

I would also like to request a better zoom function. I feel like the one we have now is quite bad, and it would probably be nicer to have the same zoom function as Lightroom. Click and drag, or even scrollwheel. I would just like more flexibility when I am looking into details in my image. its not quite big enough with the current zoom tool. 

Thank you!
