previewing docs in iCloud?


I want to use the iCLOUD as a secondary back up, I really do, but I'm really struggling here.
Attached is what I see on just a couple text docs. Is there no way to see what the documents are? Imagine 150? What am I missing here?

Secondly, If I do a backup of everything on the HD (100gb) and "save" to the iCloud, in order to work on something I have to download it to the computer (if I want to work off line and not on the web, especially in anticipation of a storm when the innernets goes out) right? Then upload later.

So, back to the first question: As far as I can tell when I click on the document anywhere, it downloads. PDFS however will preview.
