In regards to Personal Book Builder being implimented in the 2nd Qtr of 2010, the missing features page says:
Personal Book Builder (Improved to use the native book format!)
What does "Improved to use the native book format!" mean to me in regards to:
(1) Importing documents/resources created/authored for LDLS 3.x.
(2) Maintaining old and authoring new resources in L4.x?
Thanks for your consideration
