Inline refactoring for type aliases
Invoked just as any other inline refactoring, by placing the caret on an alias you want to inline and pressing Ctrl+Alt+N.
For now this refactoring is only available for non-parameterized types and for aliases that are used inside of the same class.
Kind projector support
Kind Projector is a Scala compiler plugin that provides an easy way to create type lambdas. Scala 1.7 plugin includes inspection that suggests to rewrite existing lambdas using the Kind Projector function syntax.
You can use the settings under Settings | Editor | Code Style to select whether you want to denote lambdas with the Lambda keyword, or the λ symbol.
