I am trying to use the taskbar shortcut editor to move some icons from one taskbar to the other as it just doesn't seem to want to pin it to the right one, but when I go in to the editor, my main monitor has a red 1 on it and is unselectable and I don't know why.
Thanks for sending that over. Your first monitor has a Windows taskbar on it, not a DisplayFusion taskbar, so you won't be able to adjust icons for it through the DisplayFusion editor.
We only support replacing secondary taskbars, not the primary Windows taskbar. You can turn on the "Show DisplayFusion taskbar on Windows taskbar Monitor" advanced setting if you would like it to appear above the Windows taskbar though
