When using Instant Upload I usually share only some of the photos that I have taken. In most of the cases I would like to see the photo maximized to full-screen to check whether it's blurry, badly lit or if there any other problem with it before selecting it. With current interface I have to click on a photo, look at it, return to normal view and select (or skip) it.It would be much better if I could swipe through photos in the magnified (full-screen) view and select or skip them there directly. Is it possible? If yes - how? Any plugins, extensions, GreaseMonkey scripts? If not - is there a way to do a feature request to Google+ development team? I think it could be useful to many people.
