This has been bothering me for a while, but I can't seem to figure out how to change this formatting. Let's take a case class as an example:
I prefer two tabs after a line-continuation; however, IntelliJ seems to force this style:
This behavior seems to be controlled by
Preferences -> Editor -> Code Style -> Scala -> Other -> Alternate indentation for constructor args and parameter declarations
You can also look into scalari-form plugin. It gives you much more and IDE independent. You are particuliary interested in alignArguments=true and if I remember correctly defaults should make the indentation as you want.
*Note, that it formats code after some sbt task, for instance
sbt test, not when you press
Ctrl+Alt+L or similiar in IntelliJ
