Hoodoo is an ultra lite Haskell IDE. If you are looking for a Haskell editor that's not a console/terminal application, give 

      Hoodoo a try. It supports Haskell syntax highlighting, smart indentation and basic text editing. You will need to install

      the Glasgow compiler collection. You can run GHCi and GHC in the IDE, the interpreter can also be used. Hoodoo is

      meant to be minimal so it does not support a lot of common IDE editing tasks, it is meant to be light. More features 

      will be added depending on feedback, or you could grab the source and add something:)
