Adds a counter controlled by a button to your Toolbar

If you need a simple counter that can be incremented by clicking a button, this extension is for you.

The counter can be set to increment by any value, positive or negative. The default step is +1 for each click.
Right-click to quickly make a -1 step or to reset the counter.

Additional functionalities (to be activated in the options page):
🔔 Notifications: you can set a limit and you will receive a notification when the counter reaches that number.
🔊 Sound: enable the sound option to hear a sound every time you press the button.
📅 Chronology: see a list with the date and time of the last 100 clicks.

Right-click on the button and select "Options" to access the options page.
