There’s a new version of Brad Choate’s MT-Textile plugin. Not too much that id use myself – I don’t tend to do that much formatting, although the footnote support looks handy, and would probably eliminate all those bracketed asides I keep using! I’m still waiting for a way to add a title to the @href@’s generated using the @”Page Name”: syntax, although I probably should of submitted it as a feature request!

Updated: Seems I missed this in the “documentation(Textile Documentation entry for link generation)”:

Optional: text in (parentheses) following the link text, but before the closing quotation mark, will become a Title attribute for the link, visible as a tool tip when a cursor is above it.
