A new feature added to the FamilySearch.org Family Tree program is the ability to select the person you would like to see when you first open the program. Most of the existing desktop genealogical database programs have always had this feature, but it is a new innovation to FamilySearch Family Tree. The process of selecting the starting person is quite simple and involves entering the start-up person into your preferences file.
The complete process is explained in detail in a blog post by Jeff Hawkins entitled, "Selecting an Ancestor to Appear in the Main Position When You Sign In."
FamilySearch continues to add functionality to the Family Tree program and it has become very full-featured. However, the basic issues with the merge function and the attachment to the New.FamilySearch.org program have yet to be resolved.
