I am using another JetBrains product, PHPStorm, on the Mac at the moment for some Front End Dev, which is another IntelliJ based product. This has recently become quite sluggish and is starting to annoy me, after all, who wants the tool to get in the way of the work. I hope this gets sorted soon.
That said, I think JetBrains do a great job focusing on develop tools and I've used their dotPeek product to untangle the mess left by the absence of release control in a recent contract.
