There are a few pedigree layouts and options available. Go to Preferences->Printing=>Pedigree to switch. There's a little preview button next to it as well.
This is too early to mention, but ah well. My next idea is to provide a pedigree creator where the user can add the items they want (address, pigeon info, number of generations, ...) and move them around the page how they like them. Giving extra options to change paper orientation, text and line colours, fonts and fontsizes, etc... This will give endless possibilities on how the pedigree looks.
