One of the huge features missing from Android at its initial launch was proper widget extensibility -- as far as the official SDK was concerned, what you saw on the home screen when you took your phone out of the box was what you got, no questions asked. Fortunately, this is a marquis addition in 1.5, and the official Android Developers Blog is detailing exactly how this is all going to go down. In short, it looks like devs have complete control -- as it should be -- with the ability to infinitely tweak widget update intervals and appearance. As any G1 owner can attest, this action can't possibly come soon enough.
