Meson - Center Window Utility

Minimalist utility to instantly center the active window on its current monitor.

Overview

Meson is a minimalist GNOME Shell extension designed to do one thing and do it perfectly: center windows.

It calculates the exact center of the current monitor (where the window mostly resides), respecting the system's work area (Top Bar, Dock), and ensures the window title bar is always accessible via safety clamps.

Features

Category	Description
Performance	No animations, no indicators, no background polling. Zero resource usage when idle.
Smart Logic	Calculates center based on the Monitor Work Area, automatically excluding panels and docks.
Safety	Safety Clamps ensure window title bars never get pushed off-screen, even for windows taller than the display.
