I suggest that the Kotlin plugin for IntelliJ have the field "Main class" be renamed to something like "Main package".
Why: I spend hours going in circles because I couldn’t figure out how to set up a Kotlin configuration in Intellij. I couldn’t figure out what I was supposed to put for the “Main class:” in my run configuration. It’s a misnomer because it misdirects people to thinking that they need to create a new class with a main function in it, when what they need to do is put in the name of the package that contains their main function.
It could also help if the wizard for creating a Kotlin project provided you with a small main file with a “hello world” and configuration already set up.
For reference: I know about the right click menu NOW, but for whatever reason it wasn’t showing up when I was first trying to figure things out.
