Mac OS X: Multitasking on a Mac always has everyone scrambling to find the best methods for divvying up the screen space they've been dealt, and it's not always the easiest thing to do. Moom is a small app that tries to make things easier by displaying custom window-placement options for apps any time the user triggers it.
By just hovering over the maximise button (the "green light" at the top of app windows), users can choose to fill the screen with that window, fill one half of the screen, or even just a corner of the screen. There's also an option for reverting the window placement, in case a temporary layout change is needed.
Everything is customisable in Moom, and it works with dual-display setups as well. The free demo can be used 100 times, and the full version only costs $US5.
One of the better features of Moom is how it's nearly invisible. Unless you specifically choose to keep it in your menu bar, there's nothing on the screen to remind you that you're using an "aftermarket" app to alter your OS X window functions. Bringing up the Moom menu is quick, and when Moom resizes or moves your windows, it's instant.
The keyboard can also be used in Moom, and for different things. You can set up your own keyboard shortcuts to place the active window just as the menu would, or you can move the entire window for precise layouts. The bottom line: Every function, menu, and indicator of Moom looks like it's part of OS X—and it probably should have been.
