🚀 Getting Started

Installation

Copy the plugin to your BrainDrive PluginBuild directory
Run npm install to install dependencies
Run npm run build to build the plugin
Load the plugin in BrainDrive

Usage

Add the Theme Selector module to your BrainDrive workspace
Test theme switching by clicking Light/Dark theme buttons
Watch real-time feedback with status indicators and loading states
Monitor error handling by testing with network issues or service unavailability
Check console logs for educational insights and debugging information
Refresh the page to verify settings persistence

Demo Limitation

This plugin demonstrates Settings Service Bridge usage only. Theme changes are saved to the database but don't affect the global BrainDrive theme since this is an isolated educational demo.
