Settings - adding custom class

Have you ever wondered how you enter custom classes into the new vs2005 (and vs2008) settings editor?
Or like me, desperately tried to do so and couldn’t the information anywhere.

A little information as to what I’m blathering about.
In the VS2005/VS2008 settings editor, you can specify the type of the setting from a drop down list. Also at the bottom you can choose browse to view all types. That has all the assemblies listed that you have referenced as non project references. However it doesn’t have any types listed from your project based references - annoying.

Then by accident I discovered it!

You simply type into the combo box after choosing browse, and lo and behold, it will find your types. You do have to type in your whole namespace as well though.
