Function Hoisting: Moved goToHref function outside of the "keyup" event listener to prevent redundant redeclaration, enhancing performance. Error Handling: Enhanced error handling within the "scroll" event listener to log errors to the console, aiding in debugging. Cached Selectors: Optimized selector queries by suggesting caching of reused selectors outside of event listeners to minimize DOM querying overhead, though not reflected in the code. Debouncing: Introduced a debouncing utility to the "scroll" event listener, reducing the frequency of updates to the reading progress indicator and thereby minimizing computational strain. This debouncing utility employs a 100ms delay, ensuring a balanced responsiveness to user scrolling activity and computational efficiency.
…dability Explicit Exception Handling: Modified run_ebook_convert to catch subprocess.CalledProcessError specifically, alongside a generic exception catch, for improved error reporting and handling. Subprocess Invocation: Transitioned from subprocess.call to subprocess.run with check=True in run_ebook_convert, allowing for more robust error handling. Path Manipulation Optimization: Employed os.path.splitext to derive the filename without extension in epub_to_calibre, removing the reliance on hard-coded file extension, enhancing code robustness. Function Annotations: Introduced function annotations for better type hinting and documentation clarity across all functions.

There was a problem hiding this comment.
There are two keyup event listeners now. maybe you forgot to remove the above one.
