Restrict browser to single resource type?

Hey gang -

Currently working through updating from old FCK setup to new CKEditor/CKFinder.

In the olden days, I used a hack by this one fellow to tap int the old editor's file browser, to use it elsewhere. No real need for that now that CKFinder is a separate app.

But, with the old setup, I was able to tell the file browser to drop down one folder, and to only display one type of files (i.e. "File", "Image", "Flash") - I'm not finding anything on the new file browser as far as how to tell it to do the same thing.

I've got it working in general, but I need to be able to specify the resource type, depending on where in my app the user is clicking that 'browse' button.
