Apple the Dock is horrible in multiple monitor setup

I can concur with the original poster that there is a serious problem with the current level of multiple monitor handling in Mac OS. In Barney's response he is dismissing it out of hand. I have been a Mac power user since the days of the Tombstone 128K Mac, and a multiple monitor user since about 2005 or so, and it is observable that the level of competent support of multiple monitors in Mac OS has degraded, most drastically recently. The current set of issues is unacceptable, to the extent that Windows' current handling of multiple monitors (which they probably stole from Apple) is now superior. I maintain a complex state amongst my displays and workspaces, and the currently behavior is a disastrous waste of my time, almost daily. Both my monitor positions and the arrangement of the workspaces are not persistent between sleeping or logins/boots. A cursory look elsewhere online indicates that this is somewhat of a known problem, which really needs to be addressed.

You should tell Apple:

I think it depends on the settings in Mission Control — Desktops have separate spaces.

If you put the Dock on the Side, it will stay on the far left or right display.

If you have your displays stacked top to bottom, then it would stay on the bottom Display.
