Wide tables (e.g. 116 columns, 3 suggested) made curation a scroll hunt. Now the modal lists suggested columns first (stable sort on the descriptor flag, so toggling never reorders rows) and adds a filter box matching name + description, with a "shown/total" count. Selection stays keyed by column name, so the response column order is unchanged (catalog order). Applies to read-only (excluded) tables too. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
