Column Browser Filter on Thumbnail Browser Selection

[The Incredible Boom Boom]

As titled.

Column Browser selections are able to filter on the Thumbnail Browser and it'd be useful to have the Thumbnail Browser be able to follow suit through the Column Browser.

You can accomplish that by placing the thumbnail panel in the main panel.

Hmmmm... But, then the Column Browser doesn't filter the Thumbnail Browser (the other way around.) Are these settings intentional, Steven?
