Pantheon desktop is a simple and beautiful desktop environment made popular by ElementaryOS. I just downloaded Manjaro 2015 Pantheon edition from here and now testing it.

Manjaro Pantheon 2015 Desktop
Manjaro Pantheon 2015.08 seems promising. But it performs very slow on a VirtualBox. There are few applications comes with the LiveDVD. No Office Suite application but it can be installed easier later.
