Interesting: Cinch
As a Mac user, one feature I envied during a recent Windows 7 experience was Aero Snap, which lets you resize windows to full-screen or half-screen by dragging said window to the top or sides of the screen respectively. Well, there’s a shareware app called Cinch that recreates this functionality on the Mac.
The app works just as described above, with a brief animation of a dotted-line outline indicating what part of the screen your window will resize to. The increase to full-screen option is nice, because the Mac’s own maximize button (the plus on the window) is notoriously unpredictable.
Nice touch: windows return to their original size when moved from a Cinch-determined position.
Since Cinch is an app, its preferences manage start up at login or access via menu bar icon.

Anyhow, this was one feature of Windows 7 that I was impressed with, so it’s nice to have on the Mac — makes switching much less unlikely. Get Cinch here.
