I have a very low data plan, but unlimited Wi-Fi. I'd like to set up automatic updates and downloads, but I want it restricted to Wi-Fi.

I know this is an option already, but setting that up prevents me from manually forcing a download when I am on the go and want to spend some data on podcasts. I have to go to the settings and disable the options manually, then set them back up later. And if I forget, then my data gets drained.
