In site editor currently the details view in navigation sidebar about the selected entity(page, template, etc..) shares a lot of information with contents/panels in the inspector sidebar.

Details	Inspector

It would be good to merge them and see how we can eventually make a reusable component that can used in other places too. An example would be to show the inspector controls somehow in the entities list that use the new Data Views(pages, patterns, etc..).

The process should be additive and not reductive. We should add whatever is missing from the details view to the inspector controls. Some duplication already exists and it's fine to add a bit more until the changes have completed.

Details view contain a lot of readonly information in contrast to inspector controls. If some item can be made editable(ex Featured Image), it should be added with edit functionality.

The issue is not exhaustive and design can be discussed either here or on the related PRs. It's meant to be an initial break down of tasks to parallelize work and can be updated.

Design

Tasks

• Move the readonly items Editor: Add wordcount and reading time info in post card #60672
• Move the Featured Image
• Consolidate the ellipsis menu currently in details view with the main entity info(page card, etc..). Related to that could be to check the actions we have in Data Views and also consolidate with them.(PR)
• Move revisions info
• Provide a way to make the title editable, either with rich text or a rename action in ellipsis menu(will need design discussions)
• Move excerpt/description Editor: Update post excerpt panel with new designs #60894
• When the complete merge has completed, we should remove/deprecate the details interstitial page for content views. Related issue for this is the advancing site editor index views.
