I am confused about your answer.
If you have "Enable Multi-Monitor Taskbars" checked off in the DisplayFusion settings window, this will enable DisplayFusion taskbars on your extra monitors, not Windows taskbars.
I assume "checked off" means that the check mark does not show. But when I set this check box to not show a check mark I only get a task bar on the main monitor. Did you reverse the meaning from what you intended?
If you would like the Windows taskbars displayed, you can uncheck that setting, and enable "Show taskbar on all displays" in the Windows taskbar settings.
When I uncheck that setting, the "Taskbar Mode" field is no longer selectable -- the dropdown doesn't work. So I can't match what I see with what you say.
As for replicating the pinned icons, we currently don't support this on the DisplayFusion taskbar, but we do have it open as a feature request, so I've added your vote to it.
What I want is for all of my monitors to have the exact same controls in the task bar on all monitors. I don't want to have to hunt across different monitors to find the buttons that I plan to use.
I run with the "Links" toolbar turned on. I have previously asked for this toolbar to be replicated across all the monitors, and you have said no.
Some applications (e.g. Zoom) obscure the main monitor task bar when they are in fullscreen mode. I would like to be able to click on my pinned icons on either of my other monitors to get applications started without having to take these applications out of fullscreen mode. Ditto with links in the links toolbar.
Summary: my conclusion is that DF does not fulfill my expectations.
