Thanks for the great mod! I was nooted originally on 1.1, but I wanted to go stock 1.2 for a bit to avoid the problems some have. This seems like a great compromise since I mostly use the amazon market anyway.
Here's my problem: The B&N "book" icon on the bottom tray doesn't work anymore to return to your current book. It blinks but nothing happens. I seem to recall seeing something about this in the forums, but I can't find it now.
At this time, there is no known "clean" solution for this. No one knows exactly why it worked in nootered 1.1 but not in any other version. The conventional wisdom is that if you keep the stock home program running in the background (even if you use a different launcher) it still works, even though that isn't necessary on 1.1.
You can use NookHome to launch the stock home launcher and then use the N button to go back to your default launcher
However, what I've found is that eventually the background home launcher gets killed (by the OS?) and it stops working again. But, I personally found (no verification from anyone else yet), that installing ADW (even while using Zeam as my default), I can get the stock home to stay resident and keep the book icon working.
If you'd like to "test run" my klugy-but-seemingly-effective solution, I'd love for some feedback.
