Pear::Tree - Questions and feature requests

Hi there I'm getting to really like this class but I have a few requests, some which may already be in there... 1. getNestedTreeArray($root) method - producing a nested array of elements based on parent l and r for positioning. (is this possible already? 2. Pear::MDB support 3. selectAddon - whereAddon allows SQL after the WHERE, select could be in the select? Area any of these in the pipeline, or in there already and I just can't see? Thanks in advance (and for a great package!) -- Simon H
