I think that title says it all. The tool is still in beta and needs to be sharpened up a little, but this is one thing that I was hoping would have made it into the Yukon\Whidbey Product line...

Don't judge it to quick right now. Red-Gate just aquired the tool and I am sure it will be first class when released. I am very impressed with the line of tools that they have released to date.
