Thank you for the feedback. My responses are inline. 1. You cannot use spawn command to copy (line 621 ocr.js). Response: Fixed. Switched from subprocess to native Gio.File.copy_async API for all internal file duplication - cleaner that way indeed. 2. Please don't send unnecessary code (line 239 extension.js). Apologies, I missed that, was orphaned dead code. 3. Timeout should be removed on destroy and before creating a new one (line 122 smartmenu.js): [EGO Review Guidelines: Timeout] Fixed. 4. What's the reason for === 'function' checks? Those checks were initially added as a defensive measure to maintain backward compatibility between different GNOME Shell versions (specifically handling API differences in cursor management and missing methods between GNOME 45 and 46+). I have reviewed these areas and cleaned up the conditionals to use more standard checks rather than relying on strict type checking against 'function' (which is indeed a bit nasty) 5. This code has too much spawn commands. I highly recommend to create an app and make it as a dependency for this extension. You can communicate between app and the extension with d-bus: [D-Bus Guide] Please note I have done my utmost to ensure GNOME Shell main loop is never blocked, relying on multiple spawns (Tesseract, ImageMagick, Zbar) from the extension is indeed not ideal. I am planning to migrate the heavy lifting, OCR processing, and file management into a dedicated, combined standalone app or perhaps even submission as a Mutter extension - but this would be more invasive. Can we agree that I do not extend dependencies/calls beyond what I have here? A simple extension that utilizes the dependencies in this way - also has its elegance :)

Timeout should be removed before creating a new one (line 130 `smartmenu.js`). For the spawn commands, it's still a concern since extensions are in the shell process.
