Edit label (leaf) in tree

It is only possible to change the font (color/size/bold/etc) for a node on a tree, but not for the individual leaf (label). This new feature should allow the leaf text format to be edited. For example, a reference sequence and a query/sample sequence may be located together on the same node. This new feature would allow the user to highlight the query/sample text label (leaf) in a different font from the reference sequence text.
