Don't get me wrong - it's great, especially the recent update that allows you to manage your containers a bit more. BUt for some dumb reason, there's no way to add sites to the list without opening them first - so I have to add support.google.com, mail. google.com, and so on, instead of just typing in https://google.com or *.google.com. I can't for the life of me understand why this feature would be left out. I'll be keeping an eye on this, but I can't use the "Limit to Designated Sites" feature without it.
