The whole intermediate CSV file approach is generally unattractive to me -- and also unnecessary, as it turns out.

Basically, the conceptual model (and functionality) of bookmarks in MobileSheets is a bit at odds with my needs for them.  I have several digitized (PDF) exercise/technique books that I use on a regular basis for practice.  It's particularly effective to have what's basically a table of contents that consists of links to each of the "pieces" (or sections, or whatever) in such a book, displayed so that I can move around in the book simply by clicking on the title of the piece (or page) in that table.

Since I've lately been focused on getting all my music into MobileSheets -- to the point that I've been viewing MobileSheets as a "one stop shopping" approach to my sheet music organization -- I've been adding these technique books as well.  But this is silly.

Just as MobileSheets does a bunch of things way better than trying to organize things into PDFs, PDF does some things way better than MobileSheets.  One of these is -- surprise  -- document-oriented bookmarks that can easily be used for navigation in a (PDF) collection of sheet music.  Rather than trying to twist MobileSheets' model and implementation into a form it's not intended for, the obvious answer is to simply not bring these things into MobileSheets at all, and simply keep them in PDF.  There, I can edit the bookmarks however I like, have them displayed in an easily used side panel, and use touch or foot pedal to navigate through the material.  Problem solved.
