v0.2.27

Search inside your topic guides. The Topic Guides search box now looks inside the
guides themselves, not just the titles. Type a term and you'll see matching topics plus
snippets showing where it comes up in the content — click a result to jump straight to that
spot, with the word highlighted.

Exams balance themselves. Exams now split evenly across your active study packs
automatically, and re-balance whenever you add or remove a pack — there's nothing to set up.
You can still fine-tune the mix in Settings if you'd like.

Fixes

• Print / Save-as-PDF works again from the Topic Guides viewer.
• The version number in the footer is now always accurate.
