Very nicely done, but IntelliJ seems not suitable to run on an averagely specified laptop so I uninstalled it from my laptop again (2 cores, 6 GB RAM). It is more than dead slow.
Strange, because other Java based editors - Eclipse(which is my default for Java) and NetBeans - work at speed on the same laptop. No lagging.
I'll keep it on my desktop though, that one is over-specified. Note installation of your plugin worked like a breeze on both occasions.
What are the realistic hardware requirements for IntelliJ in your opinion? You don't really mean that you need i7, 8 virtual cores and 32 GB RAM - my desktop - for this to work?
