Script to copy selected object frame/s and create new file/s at object frame size in Indesign

@SimonLeong

Does it have to be a new document? How about moving each object to a new page and resizing it to fit the object?

Hi @SimonLeong, I've written a script to do part of what you want. Maybe it will be a partial help.
