Allow customizing the toolbar on mobile

Vlad right now there's the 3 dots menu button that can't be moved from the toolbar. I've raised the issue before, but I find this to be pretty annoying because it's a button that takes up real estate on the toolbar. I feel it would be better placed somewhere else, such as to the left of the address bar, within the tab switcher, or collapsed into the address bar popup menu (maybe as an option "menu" that brings it up). This was the main reason I had given on the thread regarding customizability of the toolbar—so I could remove the menu bar. Obviously Safari doesn't have to contend with having a menu bar since the menu is in Settings.app, but I think the 3-dots menu button would be better served being on the address bar line or within the tab switcher from a usability perspective, since the other toolbar buttons are actual toolbar buttons used fairly often, while menu is more of a "settings" button. I realize as you've mentioned before that many iOS browsers do this, but I feel it's misuse of space when the address bar already has a popup menu

To be clear, I don't like the idea of merging the address bar and toolbar into 1, as that conflates their purpose, and would make gestures much more limited due to the halved area from which to start A gesture. I do think the 3dots menu should be moved to the address bar or tab switcher though
