Ability to organize fields into tabs

General Feedback

It would be nice to be able to organize fields into tabs to reduce information overload in content entry.
The tabs don’t have to have any effect on the outputted data structure.

For example, on most pages I’d like to have a tab for content (what is actually visible on the page), SEO/metadata (not visible on the page, and probably doesn’t need to be updated as often).

Looks like you can do this using Entry level UI Extensions. Similar to what they are doing in this extension with selecting a radio value to hide/show fields…
