Hi Larry,

Here are the results of my conversations with Michael.

There 3 deal with sets of objects:

VisibleSets - which allows creating sets of objects based on their being visible at the time of set creation and later restoring the visibility of the objects in any given set while hiding those not in the set.

SelectionSets - which allows creating sets of objects based on their being selected at the time of set creation and later restoring the selection of the objects in any given set while de-selecting those not in the set.

ExportSets - works the same as SelectionSets with the added feature of being able to Export only those objects that are part of any given set. My version only exports STL because that is what I do most. But it could easily be modified to export a selected file type. The path for exporting is stored in the user data of the document.

This one is deals with Styles:

StyleOps - 1. allows deleting unused styles 2. allows merging styles of similar color and updating the objects that use the color that is being eliminated to use the color that remains. 3. Allows re-sequencing of styles that begin with "Level " so they are numbered from 1 to whatever with no gaps or repetition.

If of interest and you have questions feel free to ask.
