I would like to delete some of the defaults

Which of logos are not child friendly?
Unchecking them in settings does not help?

Some of the defaults are adult-oriented. It's not a huge deal, but having certain sites listed is kind of like advertising that people go there enough to want to modify their speed dial. I would rather delete addresses and keep a shorter list removing content I don't want. I can add and increase the list, but I can't delete to keep it shorter. I wouldn't mind if I had to add every site I wanted and there be no entries at all. It's a useful extension, and something similar already exists in Iron/Chromium. I'm glad you wrote it, I just would like to remove some of the defaults.
