The extension now watches and waits for the attendance table to be populated before attempting to set up thecalculator buttons. This means it loads immediately after the Attendance view is loaded. For the same reason, the buttons are now displayed even upon switching semesters.
Under the hood, it uses a MutationObserver to achieve this.
Head over to the installation instructions and have some fun!
