The GUI is a mixed blessing. It certainly is more intuitive, but you still
rely on the docs for figuring out what they mean by snapshot, for example, to
use the CD~Rs portage snapshot:

Obtaining a Portage tree You must choose Snapshot on this screen. The
installer will automatically install a Portage tree from the LiveCD once
you select Snapshot; you do not need to specify a snapshot URI.

It~Rs not an easy task to create UIs, I don~Rt mean to be too critical.
This is a good direction for Gentoo and the UI adds a lot to the distro.
