Default action of double click in Project Explorer

When I double click on a saved Container name in the Project Explorer, it thinks I want to rename it. I would like to open the code file, preferably as the default action.

That would lose the ability to rename that way, which is also a useful feature. To get the Code Window, click on the code icon {} at the top of the Code Window.

Wow! Totally unintuitive. And totally non-Windows.
Double click is always an ‘Open’ action.
