1) The preferences tab should allow generations of ancestors and descendants (but probably not both!) to do down to zero.
2) It should be possible to suppress spouses on descendants, and show only descendants if descendant generations is one.
3) More importantly, there should be a button to print the part of the tree that is displayed, using "shrink-to-fit" landscape format. (Currently you have to use a snipping tool to produce a JPEG image and then print that yourself.
4) I would also like to be able to get a Gedcom export of ONLY that part of the tree that I have selected in this way - in other words, with all the details related to the displayed nodes only.
