Hide feature description on small screens; remove placeholder menu items and clarify saved-status comment

Make the "What it unlocks" column responsive by hiding it on small viewports (add hidden sm:table-cell to the header and description cells). Clean up Menubar by removing two disabled "Still in progress" MenuItems and update the comment to reflect the dynamic saved status display.
