Questions and statements that arise when formatting a book in LibreOffice yourself

1. Justification or ragged setting?

Strange that I never noticed that before. Thanks to the Internet, we have gotten used to reading texts with ragged right margin.

2. Are hanging indents worth it for new paragraphs?

3. How much space does the gutter require?

4. How the heck do I use different templates for the right and left side?

5. And then there are pages where the page number is displayed and those where it is not displayed.

6. I don't even know if I am using the right English terms for this stuff

7. Typography is fascinating
