As said before great addon that I use to focus on work.

Have you thought about adding an otion for enabling / disabling the whitelist from the context menu when clicking on the toolbar icon? I see that LastPass / UBlock Origin adds options there for example.

Same problem as the other ticket: children. If I make the extension too easy to disable, they will. I'd need to implement password protection... Can you think of alternatives?
