Publisher review:Slate is a free and open-source window management application similar to Divvy and SizeUp (except free).
Slate was originally created to replace the aforementioned apps due to some limitations in how each work. Slate attempts to overcome them by simply being extremely configurable.
As a result, it may be a bit daunting to get configured, but once it is done, the benefit is huge.
Detailed instructions on how to install and use the Slate utility on your Mac are available HERE.
Operating system:Mac OS X 10.6 or later
