Here are two suggestions for imports.
1) It would be really cool to be have named package imports:
import com.pkg.whatever as whatev
val x = whatev.somePackageLevelFunction()
You can already do that with objects, but sometimes you don't want to group your function within objects and have to use
import com.pkg.whatever.WrapperObject.* a lot internally. Especially since auto-completion does not kick in.
2) Extension methods could use some import-level support.
It's not rare that I want to import all extensions to a type X from a certain package. But I can't do that, you either import everything (
import com.pkg.*) or you must import your extension methods one by one.
You could put all extensions methods in a separate package (and it's really nice that you don't need to put them in a separate folder!), but again, internally you'll need to use
import com.pkg.xextensions.* a lot).
It could look something like this:
import com.pkg.(X) // import all extension methods for X defined in `com.pkg`
