ought to just be included with the strada 4.0 add-on download...

If only that were possible. A theme is a theme and an add-on is an add-on. Sadly, you can't mix and match the installers because this is what Mozilla uses to determine whether the installer is for a theme or an add-on, so jamming them both in one wouldn't work :-(
