Adding left/right swiping to navigate back and forward in Adobe Lightroom on mobile devices would greatly enhance the user experience and streamline the editing workflow. With a swipe gesture, users could effortlessly move back saving time and reducing the need for trying to tap the backwards arrow, which can be missed requiring additional taps to get back. This interaction would provide a fluid and natural way to navigate, empowering users to focus more on their creative process and make quick adjustments on the go. It's all about convenience and efficiency, making editing in Lightroom a seamless and enjoyable experience for mobile users.
