It seems that I remember that in past editions of Logos Bible software (or Libronix), resources initially opened up to the left side of the visual panel area upon initual opening. At some point, it was annoyingly (for me) changed to the right side of the panel. This makes me do an extra step of dragging it to the left side every single time. I like to have my Bible on the left and commentary on the right.
Please give us a choice how we want to open it. I would suggest a button in program settings.
Let me surmise that the reason it was changed was because Faithlife found that the majority of users prefer the right pane. Maybe, the majority of users are left brained, highly analytical people. Or maybe just the programmers are.
