elm-add-import package
Quickly add an import to your Elm file without scrolling up!

Default keybinding: CMD-CTRL-I
Note:
This is experimental and quickly developed for the sake of practicality. Currently importing specific type constructors is not supported (like Foo.Bar exposing (Baz(Blah))) but you can easily import all type constructors of a type by entering something like this in the text box: Foo.Bar Baz(..)
