I'm glad to see that bugs are being fixed, but the bug I originally opened (which was marked as a duplicate of this) was just made worse.

My multi-monitor setup is such that it's very inconvenient to do any work on the leftmost monitor. It's true that I had issues with having the launcher on the monitor on the right, but at least I could easily access it! With the launcher on the leftmost monitor, there's simply no way I can use comfortably use Unity.

I agree with Tal Liron (emblem-parade). I would rather put up with not being able to keep the launcher open, and any other bugs associated with the design limitation, than be forced to have the launcher on the left most screen. And, if this isn't possible, some serious thought should be put into the layout of Unity to see if there is a better way to place things on the screen.

While I appreciate that the bug is being fixed with good readiness, I agree with the critics on the design choices. This solution is respecting the 80/20 rule, making most of the people happy with the quickest fix, but we really need to think about these design limitation, since Unity is going to be the default environment for most of us.
I mean, every dock in the world is movable around the desktop (at least the corners), why shouldn't Unity's do the same, to make power users happy? I agree with the default setup anyway, it's great for the wide screens we have nowadays.
Keep up the good work ;)
