Hello,

I'm pretty glad to see that it is now possible to add a level floor.

[\:D/]

Since it used to be impossible with previous versions, I had created my 2 floors in 2 separate files.

How can I merge those 2 files now to create 1 complete file with both floors ? It seems like I cannot simply copy / past from one file to the other [:-/]
