Doesn't support side by side windows.
Con Limited window sizing capabilities
You can use 1/2 of the screen vertically and horizontally (divide into 4 parts). You can also use the screen in thirds too, but only the left and right third: you can't use the 1/3 in the center. There is no way to do a more granular distribution.
Con Not maintained

Con Doesn't work with any Adobe products
There are some apps like Adobe Reader that do not work with Spectacle. Basically, any app with a heavily customized UI that breaks OS X accessibility will not work correctly under Spectacle.
Con No Longer Maintained
Bare Bones, the developers of TextWranger, recently ended maintenance and support for the product. Per the Bare Bones website (https://www.barebones.com/products/textwrangler/): "We have sunsetted TextWrangler, and we encourage anyone interested in TextWrangler to download and use BBEdit instead."
Con Not Compatible with macOS High Sierra (10.13+)
Per the Bare Bones website (https://www.barebones.com/support/new-os.html): "TextWrangler is not compatible with High Sierra. We suggest that you use BBEdit as an alternative . . . ." Since Bare Bones officially sunsetted the product, it will unlikely be compatible with subsequent macOS release versions either.
