Currently, the overview page of a space is the own space name. If we go to edit the overview page, it is possible to change the name in the editor, but after publishing it, it doesn't change. We must have two ways to go here:

1. Allow the overview page title to get changed in fact, after editing it;
2. Disable the option to edit the overview page title when editing it.

Otherwise, our tool is driving the end user to a kind of weird behavior.
