I have just installed elementaryOS and got to the office and run into some dual screen problems as well:
1) Dock panel - It's just on my laptop screen not on the external screen which for me IS EXPECTED BEHAVIOR, please whatever you do, make sure we can choose to have the panel just on one screen. I have had some doc panels before and some of them force the doc panel on both screens
2) Hot corners - Hot corners unfortunately "stop" working. On external screen they are not activated at all, on the laptop screen they still work, but they change to a very very small area. Therefore you need to try out and be careful where you "bump" your mouse. This gets a little tricky, as I am using setup for my screens where one is on top of the other, so when I try to bump into top-right-corner on my laptop to use hot corner, the cursor moves to the top screen. I would still like to use the hot corners though, but I understand that there is probably no logic way to solve this...
3) Gnome Do - When I summon gnome do on my laptop screen, it is aligned to the bottom of the screen with more than half of the gnome do below viewport/invisible. I think I have seen the same behavior in vanilla ubuntu 12.04 so I think its ubuntu/gnome-do issue. I remember the ubuntu 13 did not have the same problem.
4) Top panel - I am using the minimalisting Wingpanel. The panel shows only on the laptop screen but not on the extrnal screen, which I would love to have. This issue and the Dock Panel issue above can be changed by moving "active monitor" stripe in displays setting to the external screen, but then it just switches everything to the external, so same issue in the other way.
I think thats all I could think of for now. It would be really great to see some improvement in dual screen management. All linux distros are not very solid in this matter, while when I was on windows, all I had to do was plugged screen in and everything was perfect.
Otherwise, awesome job on elementary, finally PRESENTABLE linux distro :)
