I hadn't even heard of it (well ok, wasn't doing C++, but still) but I'm generally amazed since I started using it.

I don't miss IntelliJ really, and I've had it as my go-to IDE for like 7 years. Even the VIM mode works good enough.

Interesting. When I investigated it a few months ago I was frustrated that I could only find docs for QtCreator, and nothing about just dropping in headers and writing code.
