Just wanted to say what a great tool the eraser is!
Although I have a photographic program with an excellent extraction tool I am finding this eraser is a real gift as I can work dynamically within my layout.
If I find I have taken out too much, I can just paint it back in - even if I have saved, even if I have closed the program I can still get back to my original picture! Wow, how neat is that?
Great job guys!
