Add one more tab in the edit post settings sidebar

[andreiglingeanu]

Basically, I'm looking for a way to add one more tab here:

Are there any plans to introduce an API for this? Sometimes adding a whole icon from a plugin for some simple global settings for the page is just too much.

I've looked in packages/edit-post/src/components/sidebar/settings-sidebar/index.js and for now this doesn't seem to be possible to achieve.

Thanks!
