In the same vein as this, if you highlight a node currently in your view, and you use your Up/Down on your keyboard to navigate from there, the tree will not scroll to keep the currently selected node in focus. So, if you open up your Album node, and the last node you can see is "ATLiens (Outkast)" and you select said node, push down to try and go to the node just below it (which is 'off-screen') and that node is indeed selected and the contents are filled in the main window, but the tree does not move and show you this node.
Just thought I'd make a note of this. Keep up the great work, 3.0 is coming along nicely.
