I noticed that when you drag a tab, an image of that tab appears on your mouse cursor. At least on Mac, that is. However, you can't actually do anything with this image. I would like this image to represent a screenshot that can be drag/dropped into other apps, in order to super quickly and easily show other people what's going on in a tab. I think this would be a really intuitive feature; just imagine wanting to upload a picture of the website you're on to a group chat, and simply being able to drag, tab over, then drop!
