I would use both. On my phone I would by pass the WiFi only and force a download for 1 news program I like to listen to when I drive home. On my tablet where I tether to my phone I would like an all so when I get home and connect to my WiFi, I can down load all. Otherwise dog catcher would download on the tether since it does not know which WiFi I want it to use.
Do you mean a widget to update one or all feeds?
