From the developer:
screenSHU is an app that allows you to take screenshots while playing games. Your screenshot will be automatically saved in the cloud and a link to it will appear in your clipboard, ready to paste. The program lets you edit your screenshot in many ways, including adding your own text, colorful frames, arrows and shapes, as well as blurring parts you don't want to show.
You may want to check out more software for Mac, such as Pipeline Control, feedDots or FogBugz Screenshot, which might be related to screenSHU.
