In Visual Assist X in Visual Studio 2013, how to expand/display the previously closed "Find References Results" pane?

I frequently encounter a minor, but annoying, UI issue with Visual Assist X in the Visual Studio 2013 development environment.

Often, after executing a Find References command using VAX, I close the Find References Results pane by clicking its X close box, in order to make more room for the main editor.

Sometimes I want to re-open the pane without re-executing the Find References search. In other words, the search is complete - I just want to re-display the pane with the results.

I have hunted meticulously through every menu, both Visual Studio's View menu, and the Visual Assist X menu. I cannot find any way to re-display the Find References Results pane.

Here are two screenshots that show the issue.

How do I re-display Visual Assist X's Find References Results pane within Visual Studio 2013 without re-executing the Find References command?

(I know it's a small detail, but it's a nagging annoyance.)

The option does exist in the Visual Assist X menu - but, unintuitively, it is under the Tools sub-option in the menu.

So, to re-display Visual Assist X's Find References Results pane (when it is hidden), go to VASSISTX -> Tools -> Find References Results.
