I would love it if they focused on performance improvements and making the editor more lightweight overall. I love WebStorm, but even on my beastly XPS running nothing but it and Chrome, it sometimes hangs doing nothing. I'm starting to investigate other editors such as Atom because of this. I find it hard to believe that a quad core, modern computer can possibly have a hard time running a text editor.
I hope they're going to fix the Scala and Play plugins. Unfortunately they say nothing about it. Sometimes the lag between typing and actually seeing it in Idea is a couple of seconds.. Still better than the last time I tried Scala IDE (eclipse) though.
Is this another minor release disguised as a major release in order make old customers renew the licence?<p>I say this because I did not notice any major improvements between 12 and 13, but still I had to pay for a new licence.
Is there any discussion about IntelliJ supporting multiple open projects at once? Requiring a separate window for each project breaks down when I've got 21 projects open, as I have now in NetBeans.
