Link to Parent Item in Mind Map View

I like how clicking on items in the Mind Map view will zoom into them, thus allowing you to “dig” into your graph of items.

However, having to move the cursor to the top of the page to go up the tree is a bit clumsy. Rather I’d like there to be a link attached to the currently zoomed item to navigate to its parent. This way one can both dig into and out of the items in the tree in the context of the mind map itself.
