In Appworld when I choose install something you cant go back and pick something else... You have to restart appworld.....

Once you have installed the app, you can goto Featured, Categories, as you are already in My World. I don't think you have to restart App World.

Nope. No need to restart. Select Featured or Categories, as ZombieBerry said, and you can browse for more titles without restarting AppWorld. However, is there a back button to move to the previous page after downloading an app? No, there isn't. At least not yet. As the OS is still evolving, just give it some time.

Can't you just use the back button right of the trackpad?
Used to work for me, I think.

We're talking about the PlayBook, not a BlackBerry phone.
