There is not too much to be shown (as screenshots), as it is basically a tool to help you move windows, resize windows, push windows between different screens, etc... The best (for me) is to check the comprehensive documentation provided on GitHub (https://github.com/jigish/slate/blob/master/README.md), and, even more, to play with the configuration file (~/.slate) to see how it works. You can find also on GitHub a default configuration file, which gives a nice overview of several features. Cheers.
