To make up for yesterday's documentation faux pas, when I referenced Kan's blog as a source for the debug feature over Leslie's fine official documentation that had come out some time before Kan's blog. Apologies again Leslie! I noticed another new feature that I was unaware of in the New Features guide for 10.1.3.4.1. The ability to remove the BI Publisher header from the user interface so you can get this:

instead of this.

Useful? If you wanted to host BIP inside another application such as a portal or custom app, you can make the BIP UI app look much more integrated. By default you still get our 'blue' look and feel' but I have documented else where how you can change that.
For instance, now you can have BIP hosted inside a BIEE instance and provide access to all the reports a user might wish to run with very little effort rather than picking and choosing what to bubble up to the dashboard.

How do you do it? Get on over to the New Features guide and find out, there are some other goodies there too. Note to self, RTFM!
