With WebHints enabled, every time you open one of the main views that can display the light bulb or return to it from Edit Person, a fresh query is sent to FamilySearch and MyHeritage for everyone in the view and the light bulbs disappear while results are awaited. If there are many people in the view, it can take quite some time before the focus person's light bulb appears or reappears. Moreover, it has become evident that MyHeritage stores information about the people transmitted by the query for an indeterminate period, including for the living.
This is to request that a manual mode be added to WebHints and that it be the default mode. The manual mode would provide a hotspot and icon where the light bulb currently appears that when clicked launches the WebHint query for that person. This feature would help to satisfy some users concerns about privacy of information while allowing them to exploit WebHints on those people in their database for whom they are satisfied they have no privacy concerns. It also can result in speedier response for the person of interest because only one search query need be sent.
Having this manual mode (or having WebHints disabled) as the default for new databases and first-time opened databases protects the user from inadvertently transmitting information that they deem sensitive. They have to consciously enable WebHints and initiate a query.
