If you don’t like full-screen apps because they hide the menubar, or you’re using Snow Leopard and you need to increase screen real-estate, here’s a few tricks you can try.
2. You can hide or collapse the toolbar (that’s the top part of the app that the indicator lights and other icons sit in) in some apps by clicking the elongated button on the far-right of the toolbar (if present). Alternatively, if there’s no button, look in the menubar at the top for ‘View > Hide Toolbar‘. While you’re there, look for ‘Hide Status Bar‘, which is the strip at the bottom of an application window.
3. Try either right-clicking or ‘control’ clicking anywhere on the toolbar and experimenting with the options. Some apps will let you hide the toolbars (like Office for Mac), while others give you options such as ‘use text only’ to remove icons which will reduce the size of the toolbar. Experiment to see what works best.
