A productivity assistant for Classter

Classter Ninja is a lightweight productivity extension designed to make working in Classter faster, smoother, and far less repetitive.

Instead of navigating through multiple clicks and menus, Classter Ninja places a small floating assistant inside the Classter interface. From there, teachers can access powerful shortcuts, automation tools, and smart navigation features that streamline daily workflows.

The ninja appears as a small icon that follows you across Classter pages. When expanded, it reveals a control panel with tools designed specifically for classroom management and attendance handling.

The goal is simple: reduce friction, save time, and make Classter easier to use.
