-* Make `attrs` attribute work;
+* Make ``attrs`` attribute work;
 * Make action attributes work (create, edit, delete) like in form and tree views.
 * When grouping by m2m and more than one record is set, the timeline item appears only
   on one group. Allow showing in both groups.
 * When grouping by m2m and dragging for changing the time or the group, the changes on
   the group will not be set, because it could make disappear the records not related
   with the changes that we want to make. When the item is showed in all groups change
   the value according the group of the dragged item.
+* When an item label does not fit in its date-range box: ✅ the label correctly overflows
+  the box; ✅ clicking anywhere on the label allows moving the box; ❌ double-clicking
+  the label outside of the box does not open that item.
