Latest Feb2025 - Universal-binary

Further, significant, speed improvement,
More than 60 file extensions supported -no interference with actual opening of the files,
proper selectability of text,
Still missing customization of colors but now in the loop,
No resource hoggage, no main thread blocking.

Universal Binary, Intel and Silicon.
Can see UTI types embedded in the info.plist of the extension, if you need a custom extension, let me know so I can resign the extension.

If you update, make sure to replace (or delete) the older app in its original location.

Silicon/Intel-2025January-fixed

Still an early release, but functional.
Unzip, launch once the app -or move it to /Applications beforehand ifyou need, then quit the app.
Uninstall: remove the app

initial release, silicon/intel

Installation instructions:
