Great answer to window snapping.

Snapping windows side by side was one thing, I mean, one thing that I missed from switching from a Windows 7 PC to a Mac. This app does exactly what I need: quickly resizes windows to fit them on a single desktop without having to maximize both windows and merge them like the new update for OS X El Capitan allows. It’s neat, but takes too long for something you want in a hurry. Magnet makes me not miss Windows 7 and as of right now, is a great improvement for OS X’s answer.
