<li><font face="arial, sans-serif"><span style="border-collapse:collapse"></span></font><span style="border-collapse:collapse;font-family:arial, sans-serif">Add a "search" function that allows searching for a symbol by name. (This one's not trivial due to the lazy construction of tree nodes. Basically what it needs to do is walk the tree (avoiding cycles), and call treeCtrl->SelectItem and treeCtrl->EnsureVisible on the node whose caption contains the search string. I have some notes on how to do this.)</span></li>
