Scala and Play support is already vastly ahead of where it was just 6 months ago, but there's definitely more room for improvement. The overall intelligence of the IDE is still sorely lacking versus what you get for, say, Java. I'd love to see a lot more support for intelligent editing of SBT files, more intuitive ways of finding usages of instances and types, working with implicits, and refactorings that align with Scala's abstractions. It seems like such a powerful language should have an IDE that gives you more ability to access those features.

Also, I find the code style settings to be extremely difficult to tweak, in large part due to poor browsability and also because you can't actually see them applied to the example code next to the settings editor.
