Pinterest is adding a couple of new features to help you get more use out of it. First, the app now (finally) allows you to pinch to zoom in on Pins, which it said in a blog post is one of its most requested features. Not surprising as it has been building itself to be a visual search engine and the lack of zooming ability has been noticeably absent. It has also tweaked its visual search tool, which lets you select an object within a Pin and find items that are similar. The visual search button has been moved and made to be more noticeable. Pinterest says that in tests, 70 percent more people used the tool after the changes were made. Finally, those using visual searches through Chrome don't need to have a Pinterest account to do so any longer.
