📖 What is blcPlus?

blcPlus is a powerful, open-source Chrome extension specifically designed to enhance the experience on the Daffodil International University (DIU) Blended Learning Center (BLC) portal. It actively monitors your session state and uses background automation to handle authentication and session longevity—wrapped in a beautiful, Material 3 design dashboard.

✨ Features

Bulletproof Auto-Login: Never manually type your credentials again. The extension actively watches for the notloggedin state or explicit login pages and automatically injects your credentials and logs you in.
Smart Redirects: Automatically bypasses the generic BLC homepage and redirects you straight to your Dashboard (/my/) if you are already logged in.
Session Keep-Alive: Prevents frustrating automatic logouts. A lightweight background script sends a silent ping to the server every 15 minutes to keep your active session alive.
Material 3 UI Dashboard: A sleek, modern popup interface with automatic light/dark mode support to easily manage your credentials and toggle the Auto-Login feature.
Developer Profile: Includes a polished developer profile view with sliding animations.
