Some of the things that changes is that it standardize the coding style, type-awareness makes it so different types of data are displayed differently, that I never have to touch the formatting, that I can have assembly errors and hints appear directly in the IDE rendering.
In the video above, I can't break away from the formatting by adding linebreaks. Suffixing a labels with -bin, -txt, -icn -chr will render the body of the label differently.
This means that would I loose a source file, I can recover the sources from the rom and the symbols file and resume working on a project.
