"""
Known bugs (TODO):
    - visualizing tabs need to differ from spaces in color
    - if scroll down to hide top content, then resize window down and then maximize top content into view, it doesn't get highlighted
    - highlight.whitspace (line 74), string index out of range if i <= ... content[i+1]

Next features (todo):
    - create new file
    - if editor is too slow with multiple tabs, try to only have one mainframe.textarea, and make editors keep text contents only
