+# 90 — Lists index: inline task add + list property edit
+
+## Goal
+
+From `/lists`, add tasks and edit list properties without opening the full list page.
+
+## What we decided
+
+- Inline add input at the bottom of each list card (Enter to submit, same as detail page).
+- Inline edit for list name and type via a small edit control on the card header.
+- Reuse existing `addItem`, `renameList`, and extended `updateList` server actions.
+
+## Depends on
+
+- 11 (lists module)
+
+## Scope
+
+- Extend `listUpdateInput` to allow `type` changes.
+- Update `lists-index.tsx` with add-item row and list property editor.
+
+## Acceptance criteria
+
+- [x] Add an item to a list from the index
+- [x] Edit list properties from the index
+- [x] Changes persist and match detail-page behavior
+
+## Notes
+
