Problem/Motivation
Navigation module does not have a capability to integrate the contextual link Edit.
Steps to reproduce
Proposed resolution
It needs to be added to the Top Bar because it's an action contextual to the content itself.
We are proposing to add it into the Tools region because it is not a primary action to be done on the page. It has been moved to that region to avoid possible conflicts and misunderstandings with the Edit button.
Remaining tasks
Another problem the UI has is that the same label: "Edit" is used both to show the contextual actions and if you're in a node (the Edit option to go into the node). And it makes it really complicated to understand what is this Edit button and differentiate the 2 of them. So decided to use the "Editable areas" label. If it becomes complicated to find the right copy for this label the discussion should be moved to a follow-up so it doesn't block the Navigation from becoming stable.
User interface changes
The Editable areas item will be placed in the Tools region, on the left side of the toolbar.
