Functions:

Sets a UV map active in each selected object. If a map with the same name doesn't exist, it'll be created automatically.
-

-
Sync Layers Order
Tries to match order of layers in each object to the active object.

Initially I glued this addon together to make lightmapping complex scenes easier by avoiding manually setting the active layer for each object, it has since became an irreplaceable tool.
