Collapses all folders on load (except the top level folder) and adds Collapse All button
As of 11/18/21, this script has been updated to target the new Qualtrics UI.
The My Projects page on Qualtrics expands all folders by default. When you've got a lot of folders, all with many subfolders, this list becomes gigantic. This script collapses all the folders on page load. It also adds a Collapse All button as the first item in the left panel. It does not collapse the "Projects and Programs" folder.
