Windows/Mac/Android: Chrome is getting an update today that brings in a few new features. Most notable on the desktop is the new ability to search by image with a right-click. Android users also get a few new gestures for browsing tabs.
Now in Chrome you can right-click any image and do a reverse image search to find it. This should be pretty handy for all kinds of things. Android users get some new gestures as well. These include the ability to swipe horizontally across the toolbar to switch tabs, drag vertically from the toolbar to enter the tab menu, and drag from the menu to select items. These updates should roll out to users over the next couple of days.
