Cat: a simple way to include content in your page from a resource or remote file.
Place an instance of the Cat Stack in your page and reference a text or Markdown file in your resources, and the content of that file will appear in your web page when published. You can also point to a file using a URL if you want to include content from a remote source such as Dropbox. Any time you update the original file on your Mac and republish, or any time the remote file changes, the content of your web page updates as well - along with any other instances of the Stack referencing the same file! Now supports text, html, and Markdown files, plus Sorting of input lines, searching, etc.
This is a great way to update content globally throughout your site, or sync changes to files on another site.
