"COLLAPSE (or re-expand) ALL SECTIONS" button needed

[Tony_Tsui]

Here is bookmarklet which collapses all sections via JavaScript

javascript:(function () { document.querySelectorAll('.TaskGroupHeader-toggleButton .DownTriangleIcon').forEach(function (e) { e.dispatchEvent(new MouseEvent('click', { bubbles: true, cancelable: true })) }); }) ()
