i just type right into the code editor, it's probably easier if you do all your work in some external code viewer/editor, though
i just started using Visual Studio Code recently and it's been a great efficiency tool
Highly recommend Visual Studio Code over the neocities editor, nice autofill, quality of life stuff, can work on the site without having to push to the live version immediately. Whatever works for u tho, it's all the same in the end
BEFORE I HAD TO LIKE... GO ONTO THE SPRITE RSRC AND THEN CUT THE SPRITES I WANTED OUT IN CSP I DONT HAVE TO DO THAT ANYMORE YAAAS
