Increase Sidebar Font

Just recently upgraded to Leopard, things are running fairly smoothly.

I would like to increase the font of the sidebar items in finder. I went to View Options for Finder and Preferences for Finder. None of which provided an option. Is it possible to increase the font?

I attached an image to show which part I'm talking about.

That´s what I like to know also, but I´m afraid of Apple dropped this feature!
I used it allways in Tiger, but the new Finder in Leopard has it´s own new way to handle windows, because it doesn´t remember windows-settings anymore on the fly.
In many things Leopard is a big step back to me.
