It really is not recommended to make edits in Bookview.
FWIW I use Preview (on a second monitor) to visually review the
look and sync up the code to the block with the focus in the preview.
All edits are done in code view
The only time I use BV, is when there is a pink, error box showing that I can't spot the issue. Attempting to switch, gives you the option to MANUALLY fix the code, AND that usually takes you to the problem
