On the new site, the left side of the screen is your list of cards, and on the right is the details for one card at a time. It defaults on the right to showing the details of whichever card they put first on the list.

The problem I have is that the place I click to "Sign in" with my username and password is right over something (on the next screen that draws) that makes an annoying popup appear if you hover over it. So I've had to learn to move my mouse way over to the left immediately after I click "Sign in" .

They seem to think this an improvement because you don't have to click to see some account details for your first card (or I presume your only card if you only have one card). But I find it clunky, because the supposed account details are not as detailed as they were on the old version (for example, I've yet to find where it shows my next statement closing date, whereas it was right there on the click-through account details on the old site).
