Contours ignores "Alt+B" feature of Blender

[RealMook]

When I visibly separate a finger here http://www.pasteall.org/blend/23577
I want to be able to retopo it from the front view... But it's impossible because Contours "thinks" that the whole object is still under it's "retopo area" so other fingers are in front of that separated one. The script "see" the most front finger so it makes contours around it 1st. It has a real sense...
I hope for this feature to exist.
Thank you for your work!

Thanks for the report @RealMook. This isn't on our immediate roadmap for version 1, but it's a feature I would like as well. I'll have to compare notes with @patmo141 to see how feasible it is, but it's definitely something I'd like to support.
