Why no precipitation map overlay?

I love this app, but Im wondering why there is no precipitation map overlay like you have on other weather apps. Id like to see if its raining, snowing or if its clear, and how the precipitation is moving. Zooming in and out in a precipitation view would be really cool too. The satellite overlay thats currently on the map is of no value, it only shows cloud cover (and not even very well, I might add, its hard to see the clouds because theyre too transparent). So please add a precipitation layer as soon as possible. Thanks.
