Is your feature request related to a problem? Please describe.
It is currently a pain to navigate to ~/Library/Application Support/Amethyst/Layouts from finder. The folder is hidden by default and I need to use the "Go to folder.." option and I honestly can never remember the path to type in there and I have to look it up each time.

Describe the solution you'd like
A button or menu item, something like "Open custom layouts...". This would open the custom layouts folder in a new Finder window.

Thanks for this (otherwise) great utility!
