I would like to know how to display Alphabetical section headings (i.e., A, B, C, …) of the Glossary items on the side (probably on the right side vertically). As recommended in USFM documentation, I am using \s_A for Section A, etc. In my Glossary I will eventually have many entries and I want to make it easier for readers to jump from one section (i.e., A) to another (e.g., T) to find entries that are sorted by alphabetical order. The view I am envisioning is like a Contacts list in iPhone where alphabets are vertically displayed on the right pane.
What USFM marker(s) should I use for section headings?
Is this feature available in SAB? If not, I would recommend to add it in.
Thank you very much for this wonderful software!
