I tryed it, and noticed that it is very slow, compared both with Emacs, TextPad, and Emerald. I tryed also leksah, but it is always complaining about something missing in Pango, although it works fine. Here is the error message

(leksah.exe:1588): Pango-WARNING **: error opening config file '"C:\Arquivos de
Programas\Leksah\etc\pango\pangorc': Invalid argument

Yes, I use Leo for Haskell development.  You will need to use the development trunk, though, since it contains a necessary patch I submitted to make Leo work correctly with Haskell sources.   You can download this from Launchpad:


It is possible to use Emacs as the external editor.  I don't remember the exact procedure off the top of my head, but the idea is that you enable the emacs plugin inside Leo, set your installation of emacs to start the emacs server (so that emacsclient can connect to it), and then when you double-click on a node it sends the node to emacs via. emacsclient and when you save the buffer is sent back to Leo.  One caveat with this is that Leo has a newer Qt-based GUI and an older Tk-based GUI, and I don't know if the plugin works with the Qt-based GUI yet.  You can tell Leo to use the Tk GUI by specifying "--gui=Tk" on the command line --- i.e., "python launchLeo.py --gui=Tk".

Hope this helps!
