Fonts and Typefaces

I have a failing, my memory; especially my visual memory; stinks on ice. So when I go to choose between fonts it helps me a great deal with those fonts are in their usual typefaces. That is, I can see that they look like. Telling me that they are serif, san-serif, or some other type of font does me no good. For as useful as Unicorn seems to be, I can’t really use it because I can’t really be sure how it’s going to look.

Please, put the various Google fonts you include in their typeface, and make live easier on me.
