create a "collapse all" feature within the table of content window (to the left) to help minimize scrolling
If you open the table of contents window (to the left) and read one or more large sections, such as Genesis and Isaiah in the Bible, it expands and lists all the chapters. You have to then scroll around wasting time to find the right location or close several individual books. It would be more efficient if a "collapse all" feature were available to help restore the table of contents to its original state.

This would be a wonderful help!!!!
This feature would be especially helpful for Lexicons and dictionaries, where after looking up a few terms many letters and subletters have opened, and one just wants to see the whole alphabet again.
