This is a simple and useful Chrome extension which adds buttons to event title input to mark event as completed or canceled. It is easy to use and customize.

To use it you just need to open the extension, click on the event in the Calendar, mark it as completed (or canceled) and that's it.

No more buttons in the form, no more settings to edit. This is just what you need to get things done.

There are a few options in marking your event:

• Strikethrough
• Check emoji in the beginning to indicate that the event has been completed
• X emoji in the beginning means the event has been cancelled
