CEAs for "tab closed" and "tab created".
I imagine that a lot of things in the tree that should take place on a location change, should also take place on a tab closed/created event. However, the latter would not cause a location change CEA, if those tabs get closed/created in the background. At least for me it is like that.
Not sure what else to write. If not now, maybe in one and a half months?
