Comment 3 for bug 1490958

Art,

There are two reasons:
- a technical one, explained a couple of times on kicad-dev and in this bug tracker. The P&S router uses a different geometry database than the BOARD object, and BOARD currently can't notify any other entities that its data has changed (due to delete/undo/redo/whatever operation). We plan to refactor it after the stable release and possibly add this functionality.
- nobody likes when someone calls his hard work is called silly or "downright unusable". We have no reason to respect your feedback if you don't respect us.

Tom
