Seiton

Seiton tucks rarely used menu bar icons behind a divider. Icons go into three sections (shown, hidden and always hidden), and you Command-drag an icon to move it between them. Clicking the Seiton icon opens the Bar, a small panel that lists the hidden icons; clicking one there works the same as clicking it in the menu bar. You can also search menu bar items by name and tighten the spacing between icons so more fit beside the notch. It works offline. Requires macOS 26 or later on a Mac with Apple silicon. 14-day free trial, then a one-time $6.99 for 1 Mac or $9.99 for 2 Macs (launch price; regular $9.99 / $14.99).
