The entire classic taskbar is, you might say euphemistically, heavily discouraged, having been removed in win11. Why should users who want classic functionality care about Microsoft's "discouragement"?
Why would you help people restore classic functionality, and then "discourage" its use?
Well, that's subjective. I've been using quick launch and its overflow menu from its inception and find it adequate for launching apps and opening certain frequent folders. I don't need a better way. I need the old way to keep working and to also work on the secondary when the primary is hidden by a full-screen app.
A sane default for clone mode (where the secondary task bar already shows the same running tasks and same tray icons as the primary) is to also show the same toolbars. That's more logical, coherent and useful than the current partial clone.
But for automatic moving of the primary taskbar when hidden by a full-screen app on primary, an option is needed, because that would be a new mode, which can't be forced on everyone.
