Configurable toolbar

[mxmgorin]

Let users choose which toolbar elements are shown and in what order, so a handheld can run a minimal, tailored bar. Today the layout is fixed; only position (top/bottom) and auto-hide are configurable.

Design

• Each toolbar element has an order number in [display]. Elements render sorted ascending by number; 0 = hidden. Ties fall back to a fixed canonical order.
• Settings UI: one numeric row per element (reuses the existing stepper fields) — reordering is just editing numbers, no drag/move UX.
• All elements uniform — static and dynamic alike, no special cases. Dynamic chips still render only when relevant.
• Applies live.

Elements

• Nav: back, forward, reload, home
• Address bar
• Bookmark, settings
• Chips: zoom, downloads, update (shown when relevant)
