Could be, but the features he lists are also all available in Intellij (I know because I use all of them and Intellij in the same way as he describes).
Yep it's IntelliJ. Although I don't even use every last feature of the IntelliJ platform, I just try very hard to find and use features in the IDE rather than a mix of external tools. With a terminal inside the IDE, there's not really anything I would need outside the IDE window.
Which IDE is this?
