szurkebarat, being able to show the used focus point, actually does not require a RAW converter at all. It only requires PM to understand how the various brands save the focus point information into the EXIF information/maker note. While certainly doable, this is going to require some additional research, and lots of work...
I do, however, second the request; being able to show the focus point would be a hand function, especially if the zoom function could be made to jump right at the focus point. This way you could more easily determine if the image you're reviewing has the right focus.
