I like the page action overflow menu in Firefox. So many useful features, which I don't use often, but when I do, I like to access them with a single click.
Now that the V menu can be customized, it can be done more or less, but I would prefer three separate overflow areas for page actions, browser actions and extensions. I accept that many people like to use menus for their contextual and/or organized structure, but it's more intuitive for me.
