Ok but what about kerning?

I am exclusively using this to make fonts out of custom images handed to me by a designer...
I want a narrow "," to have less air around it than a full width digit like "5" etc. It is possible to do something like that but it is hard as I have to select one character at a time, edit the xAdvance for it, then select the next one... Takes too much time!

And this tool seems directed to taking an existing TTF font and creating a bitmap font out of that, more so than using existing images. For me a full blown bitmap font editor would be more useful.
