A Windows utility that does one thing.

Centre any window.
One keystroke.

Press a shortcut and the active window snaps to the middle of your screen — or cycles through size presets. That is the entire program.

Settings

The settings window: hotkey fields for Center and Resize, three size presets, and Reset, Close and Save buttons across the bottom.

One screen

Two shortcuts and three size presets. There is no second tab, and there will not be one.

Press the keys

Click a field and press the combination you want. No syntax to memorise.

Lives beside the app

Settings are written to settings.ini next to the executable, so a USB stick carries them with it.

Defaults

Ctrl Shift C

Centre the active window without changing its size.

F9

Cycle the active window through 50%, 75% and 90% of the screen's work area.

The executable is unsigned, so Windows may show a SmartScreen prompt the first time you run it. The full source is on GitHub and builds with a single command.

The shortcuts work while the app is running. To start it with Windows, put a shortcut to the executable in your Startup folder — the README shows how. Move the shortcut, not the executable: settings live beside it.
