Looking on IntelliJ screenshots on JetBrains .com site, i found tab 'IntelliJac'.
I'm very interest that is this? :) If it not top-secret, sure.
Also i found new icon closely by run/debug in toolbar (Generics shot). Look like some dumper ;) And i also interest what this?
So, if it some debuger/profiler plugin, will be nice if JetBrains share it for plugin developers, like PSI interface - without supporting - just unofficial plugin.
