Configurable Ribbons - Add a URL or part of a URL, choose a color and a ribbon will be added to the page of any website that matches part of that URL. Here are some examples:

Configurable Ribbon Positions - Choose where to position the ribbon (top left, top right, bottom left, bottom right).
Configurable Ribbon Sizes - Choose one of 5 sizes (extra small, small, normal, large, extra large).
Ribbon Labels - Displays a label on the ribbon.

Multilingual Support - Currently supports English, Spanish, German & French, Simplified Chinese (more coming soon).
Reusable Color Swatch - The last 7 colors used will be available from the color swatch.
RegExp - When enabled the URL fragment can be used with RegExp instead of searching using indexOf.
Tab Counter - Displays the number of open tabs. Color is green when under 10 tabs and red when above. I plan to make this configurable in the future.
