This addition makes product custom options dependent. So you can set different size for different gender. Or display the file upload field if a customer wants to upload a sample.
This extension has "Option Templates" and dataflow .csv Import / Export features. So you can create a template and then apply it to multiple products at once.
Also you can upload images and add HTML note or description to an option.

To save time you can upload images directly for picker options in:
Catalog -> Picker Images (screenshot)
