I loved the Pointcast application in the late '90s. and the Yahoo Stock Ticker application.  Neither exisit anymore.

I would love to have the ability to see a selectable subset of my feeds in a streaming format at the top or bottom of the screen.  CLicking on it would open in the browser, double click takes you to the Snarfer list and catagory.

options:
Only a subset of my selected feeds
New, most recent, or #of topics
Refresh rate
screen position, font, background color
streaming speed.
