Merge Overview

This pull request significantly refactors and improves the structure and user experience of the Feedly Read Later opener extension. The main changes include a major reorganization of content.js for clarity and maintainability, and the introduction of a loading animation and feedback system in the popup UI. These enhancements make the codebase easier to navigate and the extension more user-friendly by providing clear visual feedback during operations.

Codebase organization and maintainability:

• Added section comments and reorganized content.js into thematic blocks (Constants, Utility Functions, Save State Detection, Button Detection, Entry Processing, Event Dispatching, Infinite Scroll Loading, Main Handler, Message Listener) for better readability and maintainability. [1] [2] [3] [4] [5] [6] [7] [8]

Saved entry detection improvements:

• Refactored and improved saved state detection with a new quickCheckSaved function, and clarified the logic for finding the correct "unsave" button. This makes entry processing more robust and efficient. [1] [2]

Popup UI enhancements:

• Introduced a loading animation and feedback system in the popup, including a spinner, loading messages, and visual success/error states, with corresponding CSS and HTML updates (popup.css, popup.html). [1] [2]
• Added a LoadingManager object in popup.js to control the loading animation and feedback, and integrated it into the main run flow for user feedback during processing. [1] [2] [3] [4] [5] [6] [7]

General improvements:

• Added section comments and grouped related functions in popup.js for better code clarity. [1] [2] [3] [4]

These changes collectively improve both the developer experience (through clearer code structure) and the user experience (through responsive UI feedback).
