Sometimes, I see contacts beeing synced which I did not purposely change myself. I guess, this is related to a the mixture of Android/iOS/Win7 and how they handle the gmail Contacts.
I am always worried, that something could be wrong, especially because I do not see WHAT "Go Contact Sync Mod" is changing.... I only see that a ceratain contact has been synced. I would prefer to see "Contact A, private phone synched from 555 to 666". Additionally I would like to see my sync hstory stored in a text file.
