Expand on the functionality of Create Layer from Selected Features, to create layer from the current selection in the document - which potentially could be from a number of sources.
The resultant layer might be similar to a group layer - containing the selection layer for each of the input layers.
Example of application, I need to find beaches in the statewide cadastral database. They are represented across several featureclasses, and i want to find them all without manually going through a 100 FCs. So I find on "beach", easy ... I can then select all of the found features, but I still have to manually identify each FC involved. I want to be able to create a layer file from these selected features ! That way i can map them and use in select by location etc.
Simple functionality, with loads of other uses 😃
