That's not Quick Launch. We want Quick Launch.
I feel your pain! I use a toolbar to display the Recycle Bin on the taskbar.
I like to keep my desktop clean to display art, so I use the Start menu for all my shortcuts and don't have anything pinned to the taskbar. I am still running Windows 10 on my everyday driver and Windows 11 on a test machine. Unfortunately, everything I have read about the Windows 11 Taskbar indicates that Microsoft wrote the code for the new taskbar from scratch and didn't bother to provide parity with the Windows 10 taskbar. They seem to be adding things back slowly in the Insider Development version which I run on my test machine.
I would suggest that you and the others in this thread use the "Suggest a Feature" option in the Feedback Hub and also upvote all the other suggestions for bringing back the Quick Launch Toolbar capability to Windows 11.
As far as Stardock implementing this feature, that would be great, but I'm not sure it's on their To Do list. A number of other users have suggested this in previous threads.
The only thing I can think of is to pin all the shortcuts in your toolbar(s) to the desktop or the taskbar, or as I said, create a page on the start menu for these shortcuts. Unfortunately, I don't think you can pin files or folders to the taskbar, but you can pin folders and files to the start menu.
Basj forwarded your request to the development team, but as I said, many others have requested this feature to no avail.
