Oh. Yeah. That’s exactly what I was looking for. Thanks! It works great for xml and xsl (haven’t tried others just yet). I didn’t realize that the outline plugin added folds to the text area. I searched on “folding” in the documentation and forum :)
The plugin is very useful as is, but It would be great if it provided a “mode” in which it is active, but the actual outline bar/window is hidden. That way any file types that have folding support would show the folding and those that do not (e.g. txt) would not show an empty bar. A hotkey could be used to toggle display of the actual outline window.
