While this isn't as powerful as the full plugin API, there is Edit > Find > Replace Structurally which can be used to write some pretty complex code alterations, and you can save/load templates to reuse them later.

IMO Jetbrains IDEs are the best IDEs. That doesn't make them amazing or great or outstanding. They have their bugs, their resource leaks, and sometimes just plain weird design decisions, but they're ahead of the competition by a long shot for many programming languages. Other IDEs can match what Jetbrains has to offer, but you have to install and configure every feature yourself, while the Jetbrains stuff mostly comes with batteries included.
