    BTW, if you intend to make multiple concurrent instances of EditorWindow,
    you should replace that static char s[] with just char s[].

    I made it static cause I just didn't want it to keep going in and
    out of scope on every line of data.

    Also, you can improve the speed of how it loads the data by using
    fread() instead of fgets(), so that it can load in blocks of text
    at a time, instead of line-at-a-time, which is relatively slow.
