I don’t like how paragraphs are displayed in my posts.

1. I want them to be left-justified, not center-justified.
2. I don’t want it to auto-insert hyphens in words when it breaks lines.

The current features are set by CSS files in the theme I’m using: Cactus. I’ll have to write a CSS file to overload hyphenation and justification and then change Cactus’s head.html file to include it.
