It depends on the level of integration I have with the dashboard API.
On our company we have lots of small slices and some documents that are really long and difficult to edit (lot of scrolling and trying to find specific slices) so I think that a small “skeleton” navigator below the publishing status would be really helpful. This wouldn’t need a low level integratiion.
On the Media Library add a list view with checkboxes for batched actions (delete, edit alternative text, etc). On this one, we would need access to the low level API.
I’ve sent a few requests on ProductBoard that I need to recover and I’ll post them if I can find it.
