Easel - Lecture Recordings (UoA) 作者： Matt Jakeman

Easel is an unofficial browser extension that improves the experience of watching lecture recordings at The University of Auckland. It adds useful features like an overlay for switching between lectures, video controls for skipping backwards and forwards, and a helpful "Open in Easel" button integrated directly into Canvas.

Easel is open-source software. You can find the source code at: https://github.com/mjakeman/easel
