Version 1, I've done it in a couple of hours so don't expect it to be perfect :P. Reply me at http://twitter.com/juanangeldr for any feedback.

• Responsive -so you can keep it in a side of your screen while you read your saved items.
• Some elements (sidebar, add link, top menu) show on hover.
• Option to hide like page and buttons.
• Browse link, sharing options and "text" button have been removed. Do you think they're necessary? http://twitter.com/juanangeldr.
• And, as you can see, better look: whiter, wider.

Note: since horizontal scroll bar is hidden, sidebar might not show entirely in lower resolution screens.

Tested in Chrome and Firefox, latest versions.
I use it with Autopager.
