recently paused adding features to Aero-OS to focus entirely on performance, and rewriting the core code inside js/app.js and css/style.css made a massive difference. First, I threw out heavy third-party dragging libraries and wrote a native window manager in app.js using vanilla JS PointerEvents. By combining requestAnimationFrame() with GPU-accelerated CSS translate3d, window dragging immediately jumped to a buttery-smooth 60 FPS. I also implemented lazy loading: app DOM nodes are now injected only when opened and completely destroyed on close, keeping memory usage totally clean. Finally, I streamlined style.css by stripping out expensive paint-heavy shadows and blur filters to ensure fluid transitions. These tweaks cut my initial load time down to a fast 0.8 seconds and reduced the core bundle by 70%.
