First many thanks for your wonderful and very good looking program. I use it with much pleasure.
One point though I would like to see implemented. In a large tree it is hard to keep an eye on the line to a preferrred person when navigating through the tree. But when I put my mouse over a person, instantaniously it tells me how many persons that person is away from a selected preferrred person. The information clearly is available.
So, would it be possible to indicate the line of relation with the preferred person for instance by making the relationsline thicker, or in a different colour? That would make it so much easier to navigate the tree and choosing the right brother or sister right away, instead of having to guess and doubleguess and retrace so many times.
Keep up the good work, and many thanks for the results so far.
