Is your Windows or macOS desktop full of file and app shortcuts you access often?
Chrome OS has something similar. The launcher is to Chrome OS what the desktop is to traditional operating systems. This realization made a difference to me. It motivated to clear the clutter and organize the icons on my launcher, which previously spanned several pages.
