As you can see, there's a menu bar for managing your Kindle apps and devices, and below that there is a section for managing your content. That is a radical change from the old design, which split the content and devices onto multiple pages and featured a text-based lists of items which had to be managed one at a time.
One lucky Kindle user reports that:
One can select as many books as one wants and then take one action for all the selections. That part is new.
I don't know about you but I found the old design to be deeply frustrating because I could only interact with a single item at a time. This made it much more difficult to manage my Kindle account, so I generally avoided using that page unless it was strictly necessary.
So has anyone seen the new page yet?
I have not, but I can see a slightly different version. And I can also report that there is confirmation coming in from Twitter (here, here). Here's what I see when I go to the manage my devices page:
I'm pretty sure that what you're seeing is not the final page but a misplaced component for that page. That menu bar is probably going to have the a manage my content section below it (that's what the first screenshot suggests, anyway).
It's my guess that Amazon is rolling this new updated page out to a few users at a time. I'm still waiting to see it myself, but I have found a screenshot on Twitter which shows that the new page might also feature a list view:
So has anyone seen the new page? What do you think?
