How to use it

  • Put the most-used action in the left body and hide the rest behind the caret
  • The menu holds only variants of the body's action (Save / Save as)
  • With just one hidden item, two plain buttons read better

Watch out for

  • Name the caret too — 'More save options' inside dc-sr
  • At the right edge the menu runs off screen; flip its side there
  • Built on details, it opens with no script at all
