This was the first Chrome extension I developed. I needed a counter that could be incremented by clicking on a button on the browser’s toolbar, but surprisingly I couldn’t find such an extension in the Chrome Web Store.
The counter can be set to step by any value, positive or negative. Default step is +1 per click.
The counter also has a notification functionality: it is possible to set a limit and receive a notification when that limit is reached.
Right click on the button and select “Options” to access the options page.
