I realize this is not a super important problem. It is however time consuming to scroll down through 45 books of John Piper to find one by someone whose name begins with R.
Something like the following would be great:
Lucado
McArthur
+Piper
Apologetics
Christianity
Heaven
+Rogers
+Spurgeon
All of Grace
In Defense of Calvinism
Lectures to my Students
Morning and Evening
The authors with the + in front of their name would all be lined up evenly unless they were expanded.to reveal all of the material.
Any help?
