The app is super!
But I have a suggestion to make it better:
the idea is to divide the export of pdf-file:
1) leave it as it's now: export pdf for different types of tree according to chosen relative on tree
2) make special button to export pdf-file with full information including:
1.the full tree with all people displayed on it - on first page/pages
2. in separate blocks for every relative all info about every this relative (date and place of birth, media, education, profession and so on) - on following pages
