add tag code line (#1, #1-3).
Tag behavior: on mouse hover show popup with code for that lines
May be feature to paste part of line to comment on alt + enter
Hide *if __name__ * section.
If section is big, it is boring to scroll between code and comments.
Or hotkeys to navigate between comments and code
