One of the features I was most looking forward to with the release of Mavericks was the promise that I could have access to the menu bar and Dock on every monitor. It might seem like a minor tweak, but it's always annoyed me that I had to pick one of my screens to be "in charge" of things, when I'd prefer to be able to launch and manage my applications from either screen, depending on which one I'm working with at the time. The promised top menu bar multiplication has arrived as described, but unfortunately the "Dock for every screen" bullet point comes with a big, fat asterisk.
You see, I'm one of those weird people who doesn't let his Dock sit at the bottom of the screen -- I like my Dock to sit vertically on the side. The way the multi-screen Dock works in Mavericks requires you to place your mouse
