SmartSystemMenu enables a variety of functionality to all windows on your machine. When you click the top-left corner of any window, you'll see available visual effects such as resizing, transparency, alignment (such as moving to the lower-right corner). Window movement functions include as sending to tray, staying on top, and the ability to drag the window without using the top bar ("drag-by-mouse").

The program also supports system functions such as window information, saving a screenshot, copy text to clipboard, and process priority. An available launcher menu can be customized, and SmartSystemMenu can be disabled for individual programs.
