MenuEverywhere helps power users--and anyone else with multiple monitors, or just a very large monitor--get quick access to an application's menu bar, from any window or any screen.
MenuEverywhere works in the background, with a slim CPU footprint and an extensive set of preferences to control its appearance and behavior. You can set MenuEverywhere to put a complete menu bar on the top of every window associated with an app (for example, the Photoshop menu bar on every Photoshop window, no matter which monitor the window appears in), or you can have it just place a single "Menu" button on the top of each window, with the other menu bar headers nested underneath in drop-down menus. You can have the button (or buttons) visible all the time, or invisible until you mouse over them, and you can also have additional menus only appear on secondary monitors. Probably the coolest feature in MenuEverywhere (especially for keyboard-addicted power users) is the ability to invoke an app's menu bar with a hot key or a programmed mouse button, at the current mouse location--which you can then browse through and use with your arrow keys. An optional ignore list lets you exclude certain apps from MenuEverywhere.
Most users won't find a need for MenuEverywhere, but for those who do, this app can be a tremendous time-saver (and a welcome relief for overworked mousing muscles). Recent updates have made the app's performance even faster and smoother.
