Context changes - Expand/collapse zones such as "User", "Calendar", "Navigation", "Settings" are not being announced as opened or closed to screen readers users. It would be useful to rely on aria-live="polite" to tell screen readers if the zones are "live" (opened or closed) or provide another similar mechanism.
Provide guidance - Menu elements in the right sidebar can be activated to open a submenu, but screen reader users are not made aware of this - as these links don't lead anywhere, they should be coded using the <button> element instead.
