I would like you to consider a new PCB board view mode. This mode would flip the board over for a view from the bottom layer side. It would aid in trouble shooting the board.This mode would have all the current display feature as the top layer view currentlly used but be from the prospective of the bottom layer. It would also be useful for laying out boards with componets on both sides of board.
Brand new interactions and interfaces. 
Easy to use and quick to get started.
