org-inside has been merged upstream.

This is going to be a built-in analogue of org-appear package, but less intrusive.

org-inside-mode makes it easier to edit entities with hidden contents like emphasized text, links, and super/subscripts. It alters the appearance when point is "inside" elements with hidden contents, so you know where edits will occur. The appearance is configurable, and can include face, cursor type, and unhiding ( automatic or toggled via C-c C-c).
