I would love to see available versions of NIV, MKJV, and adding Matthew Henry's Concise Commentary and Treasury of Scripture Knowledge would really make this  program perfect!! Please and  thank you!

NIV is taking a while, because the publisher has not yet given us permission.  Some publishers move very slowly.  I'm not sure of the status of the MKJV -- I'll have to check on that one.

Matthew Henry (both Concise and Complete Editions) are coming with the 2.0 release, as is the Treasure of Scripture Knowledge (plus many others.)
