Removing radius searches has essentially rendered ITA useless to me. I never have needed to use it for mileage running and I have also never used a 2000+ radius but most of the times I go overseas on holiday I am entirely flexible on dates and cities I want to visit. ITA was the only way to easily hunt for well priced fares to a region for various lengths of stay any time within a particular month.

Well done ITA/Google for killing a once very useful tool.
