Working for decades with Commodore C128, it was impossible not to notice how everything, and under everything, I actually mean the EDITOR! It was significantly all slower on ATARI-800XL!

That is basically the first thing you probably also would wanna change.
{Later i noticed that also long-time Atari users made a script which is allowing them to do the changes
during the boot time}

I don't use Atari daily, so this version below are fine for me:
