Please look on this bug.
When I make a <br> in the txt file for a new line within a verse at the end of a verse so that the new verse comes on a new line without the ¶ (paragraph) mark. Then in Accordance if I make every verse on a new line. It has always a space line on the cmd-T as "single verse". See pic.
2nd often/most in the reader modus the ¶ within two paragraphs don’t separate them in two.
The quantify for ¶ can be higher in the User Bibles, before Accordance complains.
