Having the logs removed from this navigation is incredibly annoying. Particularly when you are in a support role. 

The advantage with the <4.0 version was that the activity was pre-selected on the logs page. 

Now, I have loads of clicks to get to the logs page and then I have to find the activity in the drop down. In a long/complex course this isn't trivial and is error prone. Activities are not ordered alphabetically and can have similar - or even the same name (there's nothing to enforce unique names in courses, remember).
