Comparing trees, there is no way to copy (create) empty directories from a pane to the other.

I need more information: how did you do it in flat mode? Also, tree mode is more like Windows Explorer with two panes, and I don't know how you'd do that with the Explorer.

In the attached screenshot, E:\tmp is empty and D:\tmp contains (only) an empty subdir called "foo".
All the commands to copy (create) the empty directory in the other pane are disabled.
I think previously it was possible to do that kind of copy, or my memory is cheating me?

So you are referring to flat mode... Yes, it's a bug in 15.0 Beta. The fix will go to the next build.
