Yes, please! Make the "forecast" optional!
Mixing actual data with forecast data is a bad idea in general.
With the current implementation it also seem impossible to know what you are looking at. Sometimes "5 minutes ago" seem to show an actual radar picture, sometimes it is likely a forecast, because the radar picture has not been updated yet. No way to know really, but when precipitation move into areas where there is no radar coverage it can't be an actual radar image.
A clean and easy to use radar view was my primary reason for getting Premium subscription. As the current radar view is now yet a version of the Rain Forecast view, I'm not going to renew my subscription.
Sorry, but this was a really bad design decision :-(
