Canvas Helper od Toby Faucher

Canvas Helper is a lightweight side-panel companion for Canvas LMS. It shows
your active courses and the assignments inside each one, so you can scan
what's due without switching tabs or hunting through Canvas's navigation.

Features:

• One-click access to all active courses
• Per-course assignment list with due date, points, and submission status
• Filter assignments by status (all / not done / done) or by name
• Live name-match highlighting
• Remembers your last selected course and filter across browser sessions
• Works with any Canvas instance (any *.instructure.com subdomain)
• Auto-detects which Canvas you're logged into — no tokens, no setup

How it works: the extension reuses your existing Canvas login session to call
Canvas's official REST API. Nothing is sent to any third party. All preferences
are stored locally in your browser.
