User Interface Quick Navigation Usability
 

This is simple, but I hope it gets changed...

In vB3 the quick navigation (the dropdown at the bottom of the forums when you're viewing a thread or something) had the dropdown and then a "go" button.

In vB4, it has the dropdown and then a "Top" button.

In vB3, you were able to read the thread and then click the "go" button to be able to return to the parent forum (of the thread).

In vB4 I have to either scroll up or hit the "top" button and then click the forum from the crumbs.

It seems minor but I think the way it worked in vB3 was much easier and frankly, better.
