It would be nice to allow modifying buttons in the menu that appears when pressing site favicon on the address bar.
Similar to toolbar, it would be nice to choose what is displayed in site menu. There are many features that there that I personally do not use much (e.g close tab, time machine, hide toolbar, site settings, add bookmarks).
It would also be nice to allow moving items between site menu and toolbar. For example, I would want to move share menu from toolbar to site menu to reduce the number of buttons in the toolbar.
