Advanced GNOME notification capabilities including rate limiting, custom color theming per application, and notification positioning

• Notification Rate Limiting - Prevent frequent notifications from the same app within a configurable time threshold
• Notification Filtering - Block or hide unwanted notifications using regular expressions to match title, body text, or application name
• Custom Themes - Set custom colors and font sizes for notifications per application using app names or RegExp patterns (background, title, body, app name, time)
• Notification Positioning - Control where notifications appear on screen (fill, left, center, right)
• Notification Timeout - Configure auto-dismiss timeout for notifications with idle state handling and urgency control
• Fullscreen Notifications - Enable or disable notifications when applications are running in fullscreen mode

• Install Extension Manager
• Search For Notification Configurator in Browse tab
• Select the extension and click Install

   gnome-extensions enable notification-configurator@exposedcat

   Or use GNOME Extensions app to enable "Notification Configurator".

1. Setup development environment:

   npm install

2. Start development session:

   npm start

   This will:

   • Compile TypeScript sources

   • Launch nested GNOME Shell session for testing

3. Debug the extension:

   • Check terminal output for logs in the nested shell session
   • Access Looking Glass debugger with Alt+F2 → lg for interactive debugging

To add translations for the extension:

1. Create a new translation file:

   cp po/main.pot po/langcode.po

   Replace langcode with your language code (e.g., po/uk.po for Ukrainian).

2. Edit the translation file: Use Gtranslator or POEdit to edit the created file and make translations.

3. Update translations when needed: In case new labels were added or original labels changed, run:

   npm run translate

   Then update your translations if needed.
