I was running Fuduntu very recently for about two weeks in my distro hopping list.
So, let me attempt at an answer to your query!
The biggest difference as far as GUI is concerned is that Fuduntu still uses GNOME 2.X whereas Fedora uses GNOME 3.X. From the comments of the developers/community over in Fuduntu, I came to know that Fuduntu does not support GNOME 3.X (yet).
So, if you are using GNOME version of Fedora, you would be using GNOME-Shell/GNOME 3. This means that there are lots and lots of differences between the two "versions" of GNOME. The particular behaviour you are referring to is the default behavior of GNOME shell. Of course, it would be possible to use alternative DEs and configure them as you wish.
Long story short - It should be possible to configure Fedora as you would like to have it. But, in my experience, many of the "effects" that were present in Fuduntu would have to be configured in Fedora.
Hope this answers your question.
