I made this visual with the Windows Snipping Tool:
The second screen shows the comparison of information for a person in RootsMagic on the left with the person in the Ancestry Tree on the right. The event entries are color coded, similar to how RootsMagic color codes with the FamilySearch Family Tree.
On the second screen, there is an index list of persons with icons that show whether each person is in the RootsMagic tree and the Ancestry Tree. That's a nice feature.
The WebHints feature is also discussed and shown - the WebHints list for each record provider is familiar, but will have Ancestry.com added with Total, pending, confirmed and rejected numbers. When you click on the Ancestry WebHints, you get a list of records and then can select each one and transfer data from the Ancestry.com record into RootsMagic, including a source citation and a media image.
I look forward to testing this when it is released.
