I would like to request that taking a screenshot be added as one of the actions that can be mapped to the side key. The reason for this is because I play a lot of games and like to take screenshots to share with my friends. However, swiping the screen isn't always an option depending on how the phone is being held, and the placement of the volume keys on the same side of the phone as the side/power key makes the Power+Volume Down button combo inconvenient as well. Samsung Game Launcher has a configurable shortcut that allows taking screenshots, but accessing this shortcut requires swiping up from the bottom of the screen, and depending on the game screen input may cause what I wanted to take the screenshot of to be missed. The only way at this time to take a screenshot with the side key is to install a third-party app that requires risky permissions and the Android Debugging Bridge to use, and that's not a risk I'm willing to take.
