I use the McLuhan Theme.
I have in all the books the skip lines between paragraphs selected (I do not know if is by default or I did change in the past). But the books are indent as you can see in the picture.
If I do change from one to the another it works in the good way, but I have to change the settins, without my hand modification do not works the selected configuration for all the created books.
The current indentation looks strange. I think if we have indentation, we have to have indentation each time we start a line, not in the second paragraph (the problem is, those are not paragraphs, are two lines of the same paragraphs as I did use the Shift Intro Paragraph).
I think a revision of those options are necesary because looks strange to me. In the past It did not works like that. we had not such indentation in the second line. And I think it was better.
Maybe instead of a radio button we can have a checkbox.
