Watermark Pages wot tommilligan

If you work on websites, you know the fear - is this staging? Is it production? Do I really want to click this "Delete" button?

This extension adds a clear watermark to the page. You can configure which pages have which watermark with a simple regex.

Currently a very basic implementation; please create an issue on GitHub for any new features you want. Currently supported:

- Regex matching for page URLs
- Custom text
- Custom text color
