Alternative to Atlas?

[Aalwein]

With Atlas losing its developer, is there another addon that features instance data or even just instance maps? I'm using Carbonite but I would like to continue to have the "full-view" of the dungeon to refer to. Atlas works ok for this purpose, but I would really like to be able to turn off instance data and just have a small map of the entire instance up. It's easy to view the minimap at maximum instance scale while referring to the "overview" map to reference myself in the dungeon.

I noticed Mapster only has instance maps for Northrend. Is there a crossover between Mapster and Atlas... one that simply has all the instances mapped?
