Adding a term in set editor is hard when there are a lot of terms

[grimsteel]

Is your feature request related to a problem? Please describe. When there are many terms in a set, you have to scroll to the top and back down to add a term, because the add/import terms buttons are at the top

Describe the solution you'd like Make the header for add/import terms position sticky

#home > form > h2:first-of-child {
  position: sticky;
  top: 120px;
  padding: 1rem 0;
  z-index: 1;
  background-color: white;
}

Describe alternatives you've considered Put the add/import terms stuff on the side rather than the top

Additional context Even harder on small screens
