I agree this would be a nice update. In the meantime, holding CNTRL while clicking the open/close take/automation icons works.
Not for me it doesn't.
First you need to select all of the tracks you want to expand or collapse lanes. Then, on any one of these hold CNTR while clicking the appropriate lane button. This should work. Unless, as has already been noted, auto zoom is engaged.
