With the new Learn-feature, you have the possibility to group each contact immediately after a call.
The screenshot to the right shows an example with chosen principle of selectively hide. The hide-groups are dominant - meaning if a contact is in at least one hide-group, your ID will be hidden.
The sheep-icons at the bottom show the actual state of the contact (left) and the overridden state (right) - they don't match at this time. You can fix it by selecting a hide-group. Then SecretSheep "remembers" your overriding.
