* The Canticles following the Psalms are not pointed for chanting.
* The order of the stuff in the daily readings should ideally have been: Psalm HYMN Readings etc. That would have facilitated its use in the daily office.
* Instead of the first Psalm Chart, it would have been very nice to have had the days and morning or evening written into the Psalter itself (with a note recognizing that not everyone will pray it that way).
That's it. That's ALL I can suggest to improve the book. No joke. And how minor are those three things, eh? Oh, I know some folks consider the ESV to be a drawback; I don't. In general, it's a very good translation and I, for one, suspect it will have some staying power.
