The updated list view is a much much better IMO.

The three further improvements I'd like to see are:
1. To enable drag& drop re-ordering and nesting from within that list
2. A contextual menu on items allowing copy / duplicate. Currently keyboard commands for copy/paste sometimes work, on some items (paragraphs, but not groups or columns for example) leading to a sense of functional confusion and disconnect "am I doing anything?!".
3. A tear-off side panel floating window variant, which is re-sizable. For cases when the list is long, and the editor needs to focus on one small section.
