@rebron Right now it's difficult to add 'Create New Profile' item without patching chromium quite a bit. However, in the next version of chromium which we'll be rebasing on, the code is much nicer to insert an item in to. So let's separate that in to a different issue. Everything else is catered for in brave/brave-core#3292

@petemill Let's add it back when it's easier to insert.
