Yes, finally with Microsoft's .NET framework and tools being no longer beta, Advanced Library isn't beta anymore, too.
Feel free to ask any questions the documentation on the homepage doesn't cover yet here. You don't need to register for that.
Have fun using AL :-)
Great work on this. It's a shame e-Frontier didn't take the opportunity to provide this level of library customisation right inside Poser 6.
One thing I've always hated about the library palette in Poser is the way it's organised into Poser File Types (Figure, Pose etc) instead of being grouped by object. Advanced Library makes it very easy to group a figure, along with all the poses, materials, morph injections etc. that go with it. I especially like the way that multiple folders can be brought together into a single "flat" view.
Tested with P6 and v1.34b8 of the RPC Poser script, and also P3DO Pro 1.7.8 Beta 2
