When there are many imports in a file and some of them don't specify the full path, it can be confusing to figure out where they are.
It would be great if you could hover over an import to see the full path. For example,

import scala.util.parsing._
import combinator._
import token._

Hovering over "combinator._" (and possible even over the "import" keyword) would show you "scala.util.parsing.combinator._", or hovering over "token._" would show "scala.util.parsing.combinator.token._"

It would also be useful to have the ctrl+1/quick fix offer to change an import to the fully qualified path.
