settings-registry
Domain: JupyterLab GUI
🎯 Motivation
JupyterLab’s system for loading and storing user settings. Extensions declare a schema and read settings via ISettingRegistry.
📋 Concrete Example
In a plugin, settingRegistry.load('myext:settings') returns a ISettings object you read with get('key').
🔗 Analogy
The settings registry is a control panel — each extension has knobs the user can tune and save.
