What is it?

SmartSystemMenu extends the system menu (the menu opened from a window's title bar icon) of every window on Windows. Once it is running, each window gets a set of extra items for common window management tasks, such as hiding a window, rolling it up to its title bar, keeping it always on top, or changing its transparency and size.

Beyond basic window control, it offers options such as aligning a window to one of nine desktop positions, moving it to another monitor, dimming all other windows, making a window click-through, hiding it from the taskbar and Alt+Tab, and changing its process priority. It can also show information about the window and its process, save a window screenshot, and copy the window's text to the clipboard.

The program ships as an executable with a command line interface, so the same actions can be scripted with options like --title, --alignment, and --alwaysontop. It runs on Windows XP SP3 and later, supports both x86 and x64 systems, and is installable via Chocolatey, Scoop, or WinGet.
