Carbonite. Be careful, though, as Carbonite is a large quest aid with several modules, including a map module (this is the main module) . You can install as many modules as you want (or need) to get Carbonite to look and act the way you want. It is very configurable, also, and is a very nice addon.
Ahhhh, the vagueries of the aging mind. Wait.... What was I saying?
Carbonite <----- GitHub main module (Maps ONLY) download link. The other modules are also available on GitHub. Carbonite-CLASSIC<----- GitHub link to Carbonite Classic. Thanks to ircdirk for this!
