This was simple enough for me to manage with my currently limited 
resources. I put in a new widget that uses two <select> fields to show 
only the relevant feature types for a given data store. This is in 
revision r784. No fancy AJAX used, just normal Javascript (using 
MochiKit) to operate on the DOM.

Could you try this out and see if it helps you. If it's useful I can 
polish it up a bit and add i18n etc.

cheers,
Kai
