This is a very simple one. It simply allows you to group lights together by their type by providing a list of those lights together. You can then modify attributes for those lights or for one light at a time.
This is very useful if you like to keep the interface hidden. Adding this script to a marking menu can be useful. This way never loose lights in the outliner.
You can now also create and delete lights from within the UI.
The following attributes can be edited on selected lights:
translation X, Y, Z rotation X, Y, Z scale X, Y, Z (changes can be made relative) visibility
node names light color intensity shadow color dmap bias cone angle (spot lights) penumbra angle (spot lights) dropoff (spot lights)
