- SortableRepeatedMixin / sortable_repeated_field.js:
- features list
- tracker field management custom fields
- tracker milestone table
- ticket-list.js which is used on ticket search results gear icon, you can reorder the columns (I didn't even know that was possible!)
The SortableRepeated stuff seems messy to me, at least the tracker field management is a very messy page. May do a proof of concept moving the features list to use the new sortable, and we can move towards dropping SortableRepeated widgets?
