1. When looking at the list of hints either for the entire tree or for an individual, it would be very helpful to have a mechanism to select multiple hints and ignore them en mass. A checkbox to the left or right with a button down at the bottom for example.
2. It would also be helpful to be able to disable hints for not just a tree but also for specific individuals in that tree. While I do want to know who married my 4th cousin 2x removed, I don't really feel the need to document his life and family.
