Even easier window management with DoublePaneSeptember 29, 2011
After I had been using Divvy for awhile, I was pointed to DoublePane by a coworker. The app, made by 5am Code, is essentially the barebones version of Divvy, adding only four simple keyboards shortcut to resize windows.
^⌥→to cover the left 50% of your screen
^⌥←to cover the right 50% of your screen
^⌥↑to maximize the window
^⌥↓to go back to the original, non-resized via DoublePane, window size
What’s awesome about DoublePane is that I had been using Divvy, a more expensive ($14) and feature-rich app, to do basically the same thing with it’s custom keyboard shortcut functionality. DoublePane was just another way to do that and only $3 in the Mac App Store, so I opted for that one.
Check it out and see if it suites your needs.
