My favorite LttD display theme is the Olive theme. I like the color and 3d effect. Unfortunately, in threaded mode, the active subject does not appear in a different color than the others--as it does in all the other themes, making it difficult to discern where it fits into the thread. I hope you will see fit to make this minor adjustment--as this is my favorite theme.
