Writing a PCB layout tool would be a lot of work; and there are already plenty 
of decent tools. If PCB support is implemented in the near future, it will 
likely be as the ability to export to PCB-layout programs.

Thanks. At the moment, there's not much that can be done to fix this in an 
elegant way - expanding the canvas on the bottom and on the right just 
involves increasing the size of the canvas, but due to the limitations of the 
underlying widget (QCanvas), expanding the top and left sides involves moving 
all the items on the canvas to the right and down as well as increasing the 
size of the canvas.. QCanvas is likely to be replaced in the future, so this 
bug will have to wait to then to be fixed (when it can be fixed elegantly by 
allowing the canvas to have a negative top-left position).
