There's a boatload of Scintilla based text editors, many of which are free, on Windows I use Notepad++ and Bowpad via Sigil's Open With. My primary motivation to use them on xhtml and css is code folding. When I use them I often wonder: "If Sigil were starting development today, would it make sense to use Scintilla/ScIte as the basis of its code editor."

However, I can't see what advantage a Scintilla plugin would offer over Open With, unless one regards having something in the Plugins menu as being significantly superior UI-wise to right clicking the thing you want to edit in the Book Browser. In which case, wouldn't it be easier to add the Open With option to the Edit menu and button bar.
