It can be useful - when the tree grows - to have a simple feature to collapse/expand branches of the tree for viewing and printing. Approximately same functionality as a mindmap tool, it gives better overview and easy to work with a branch only.
For myself; I would appreciate to be able to view and work with parts of a tree in a simple way, like click of a button. And when printing, I would really like to have better control over how the prints are generated and what to include/exclude or how the printed tree should look.
Just my 5 cents of the day.
