Option to highlight Mature sims on minimap

Title says it all. Have it disabled by default so that only those who want it need use it.

The current PG/Mature indicator on the menubar is nice, but it only shows the status of the point you are at. For people like me who enjoy wandering, it can become annoying to have to use this to gauge where PG/Mature sim borders are. If we had the option to highlight Mature sims on the minimap, we could see them approach and avoid them -- or enter them -- as we so desire.

This has been suggested in a few ways before and I don't see why something like it couldn't work. Some way to see what's PG and what's M at a glance wouldn't really hurt anyone and would help those for whom it matters.
