* Slightly better https handling in pre-embedding. (Aeva-Embed.php)
* Better styling of board stats/last post. Hopefully, it doesn't add too much CSS. But I'm saving CSS elsewhere specifically so I can add more CSS where it matters, so... (Boards.template.php, MessageIndex.template.php, sections.css)

* Topic lists are now responsive, as well as board lists inside board pages. (MessageIndex.template.php, sections.css)
! show_signatures setting should be on by default... (install.sql)
