Sometimes tabs display the short names for the MultiView resources:

Other times, tabs merely show a + sign.

This is apparently dependent on which resources are selected for MultiView. (For the LEB+, those resources were NICOT Jer NIC OT/NT series, and FSB.)
It would be helpful if the short names always appeared (provided that there is enough space to display the longer tab format). Thanks!

Incidentally, the long names also vary for the LEB:
- The Lexham English Bible is shown when followed by a pipe character
- Lexham English Bible is shown when followed by a plus character.
