I believe my source code files feature many imports that are not used in the code (as I have a bad habit of copying them from existing to new files). When coding C# in Visual Studio (or, maybe, it's a feature of an add-on of it) one can wipe out all the unused imports in just a click. Is there an analogous tool for Scala? Would be cool if I could just point it to my sources directory and it would clean all the files inside it and all its subdirs and subdirs of them (etc).

please use the default key combination below. CTRL + ALT + O ---> to remove the unused imports in windows. However, you can also change the keymap of "Optimize Imports" in settings.
In VSCode, go to File -> Preferences -> Settings and click on the icon in the top right hand corner to open up the settings in JSON. Et voilà! Your imports will now be organized every time you save a file.
IntelliJ can automatically clean up imports, not just highlight them, and for the whole directory. The shortcut is Ctrl + Alt + O.

Scalafix has a rewrite to remove unused imports: https://scalacenter.github.io/scalafix/#RemoveUnusedImports
add addSbtPlugin("ch.epfl.scala" % "sbt-scalafix" % "0.5.0-M1") to your project/plugins.sbt
then run sbt "scalafix RemoveUnusedImports"
