After 10 years of programming almost exclusively in dynamic languages I'm very much enjoying the refactoring abilities of modern IDEs when I'm doing native mobile development. I rarely have to change a method across an entire code base, but the ability to rename a method or package name in half a dozen files with a single key press is indisputably not only a productivity boost but an encouragement to more extensive refactoring.

More generally, the ability of modern IDEs to manipulate code structurally, and not just texturally, has been eye opening for me.
