I like how good Data management integration works. IntelliJ is really cool. Any time when I am required to perfom or run my code and something is not right, I am going back to intelliJ and try it there, that is how trustuble platform is.

Intellij provides a clean neat Interface for any new user coming in, and provides various build tools like, SBT, Maven, Groovy, Gradle, Kotlin. In order to build your application from scratch, you can use Intellij and it helps you suggesting more and more plugins to support throughout the development.

The GIT version control system. This is like 50% of the reason why I absolutely love webstorm and could never switch to some other editor because no other editor comes with tools for git as good as webstorm or any jetbrains editor. It's super easy to use, very scalable and I wish it was an entirely separate product by jetbrains, I'd for sure pay for it, I read in the jetbrains forum that they're not looking towards investing in making the git gui a separate app, but I'd absolutely love it. And other than git, I absolutely love the other features that comes with it, like intelliSense that automatically imports in functions from files somewhere deep in the file tree, so all I need to remember is the function name and webstorm knows exactly where the function is. Lovely feature.
