If I have several different kinds of file open — HTML, CSS, JavaScript, and plain text, for example — I want the Outline Bar to automatically appear and behave differently for each language, and for the text file I don’t want it to appear at all. EE should remember per configuration whether to show up initially and how to behave, (how to find a function to list, whether to collapse comments, etc.), and remember per file whether the user has displayed it or not.
