A simple extension to add a sticky label to the top of the page, depending on the hostname.
This extension will add a sticky header to your page with the text and color as defined, when the url matches with what is configured. Multiple labels can be configured.
For instance, if you have a production, test and dev instance of a web application you are building, configure this extension to label them as such. This would help to avoid testing in the production environment accidentally.
Currently, the configuration is just a JSON object, however the next version will include an intuitive UI to configure.
Wildcards are supported in the hostname configuration for matching (examples here: https://github.com/AlexKamaev/match-url-wildcard).
