I was just searching the forum looking for an answer to the same question - but I guess from the lack of response to your post that this is not currently an option. I can set the fretboard to be left handed, which is nice, but it doesn't seem to remember this setting, so I have to choose left mode each time I start up the program. It would be good to have left handed chord diagrams too, and to be able to set this as a default.
