I've been using ~5 IDEs for the better part of two years now. I tried to hold my leaning-tower of Eclipse together but that didn't end well. I love Eclipse because it has all of the features I need that many other IDEs don't have yet but at the same time it has one of the worst and least intuative plugin systems (funny how that works out, right?). There's no hope for polyglots I think because nothing will ever be dev…
IntelliJ is awesome for polyglot development.
IntellJ becomes a hob-cobbled mess of half complete plugins if you attempt to push everything into that single beast of an IDE.
I currently use CLion, PyCharm, PHPStorm, Project Rider and a few other JetBrains IDEs but sadly their autocompletion and features aren't on-par with Eclipse's autocomletion and integration into Java. Nothing really comes close to that in my opinion.
