Does what it says, simply. I didn't think I would need it. Then, when I was hooked to a TV screen and using the mirrored-displays setting, I was at 1024x768 resolution. Needless to say, that meant I didn't have a lot of menu bar in Safari (watching something on Hulu). I went to hit Caffeine (to keep the screen from dimming), but it wasn't visible. Same thing in the Finder. Then I remembered this app, Menuola. Downloaded it, fired it up, and voila!
Nice to have when you need it.
