Nice simple parental control (for infants), I use it with disablemenu. I just use a simple white list of allowed sites. Will need more sophistication later.
Please consider an option to white list all the bookmarks automatically. Or just the bookmarks in a folder named Whitelist. And while you are at it why not do the same for Blacklist. What could be simpler? Disable BlockSite to test the blacklist bookmarks. Might be able to hide the Blacklist bookmarks when BlockSite is enabled.
