There was a program called Grab.app on earlier versions of macOS that you ran to make screenshots.
Now there are only combinations of keys that take the screenshot. I can't remember these and have to spend some time googling for the combination, which leads me to takes me to lists of they keys including very difficult ones to access
Is there way to get similar behaviour to the way the Grab.app did this that is as a standard macOS application with its functions provided by menu. (or any other way of getting these functions on a menu e.g. services or menu-bar)
