A little off topic: even though my IntelliJ license is paid up for another month, I just signed up for the complete toolbox. Seems like a really good deal and I am happy enough with the revised license.
I am a polyglot programmer so also having the professional versions of RubyMine, PyCharm, and WebStorm is great. (BTW, IntelliJ is also my dev environment for Clojure and Haskell)
For many years JetBrains gave me complementary licenses (because of all the Java books I have written) but for the last few years I have happily paid them. I basically 'live' in IntelliJ.
