Let’s face it, multiple monitor support on the Mac has been painful. That’s set to finally be cured in OS X Mavericks, but in the meantime (or if you have no plans to upgrade to Mavericks), Aaron Ng’s Multimon 2.51 (Mac App Store link) eases the pain. Multimon adds a menu bar to your external displays, so you don’t have to drag your cursor across multiple displays just to operate your apps.
While Multimon’s main function just works – even across multiple monitors and desktops – Multimon also enables you to move windows between displays with a keystroke. Just press Control-Option and then an arrow key to move the active window to another monitor.
Best of all, Multimon remembers your window positions, so if you unplug an external monitor from a MacBook, then plug it back in, all your windows return to the same position, instead of winding up a jumbled mess.
If you work with multiple monitors, Multimon is a must-have.
