ScreenSketcher is a tool for creating quick mock-ups, or wireframes, of a user interface, such as a window, a web page, or anything that can appear on a screen. ScreenSketcher is a native Windows application, so it runs smoothly and quickly, and launches fast. It has the familiar tabbed interface that doesn't clutter your screen, and you can even zoom in and out to fit mock-ups inside the window as you like. ScreenSketcher has 34 ready-to-use elements that you can put into your mock-ups, including menus and Ribbon-style toolbars. It also automagically groups elements in your sketches: for example, if you put a button inside a box, moving the box will move the button as well, however, if you move a button outside the box, it will become a separate entity. It is so natural that you won't even notice the trick.
