// done: get a floating comment box that is not modal (you can move it around) and resizable
// GOAL: make it work on mobile XD
// GOAL: make it work with my Comment Formatting script (that means adapting the other script)
// done: make it submit the comment directly, no need to copy it elsewhere (like owl's comment from bins)
// done: cache comment text
// GOAL: choices of pseud and chapter (if viewing multiple chapters)
// done: insert highlighted text directly in comment (in italics or blockquote)
// done: character counter
// done: open it from a nicely placed button
// done: while submitting, show some sort of progress & load the page to the new comment if possible
// done: make it open at the position where it was last closed
