"General" and "Testimonials"

Under Design>Site Layout there are two tabs:

  1. General
  2. Testimonials

    As it comes with the template, “General” seems to contain a welcoming message that only appears on the first page. Not sure how the “Testimonials” is supposed to work, but when I entered something, it appeared in a block on the Homepage.

    I’m curious why the “General” text doesn’t show in Blocks mode. Is there some reason these two functions were split off from the Blocks method of adjusting the layout?

    Sorry for the noob questions; I’m trying to understand the logic.

    Overall, the Admin interface is the most intuitive I’ve found for any shopping cart (and I’ve tried a few), so kudos for that.
