opening an editor from git-gui on a file

Hi there,

Hopefully sending the question/idea to the right list...

I'm missing the feature to open a (configurable) editor with the 
currently selected file in git gui.

E.g. Looking at

I'd like to open my editor with the "request.php".

Any chance to have that? Or do I miss something?
