Version 0.5.1

- Added a "Clear index" button in Settings that removes the search index from disk, including the decrypted contents of any encrypted emails you chose to index.
- The empty search window now has a clickable "Rebuild" link to start indexing directly, instead of pointing you to Settings.
- Documentation and internal maintenance improvements.

Bug fix: resolved an issue that could prevent a search result from opening in a fallback scenario. No changes to search behavior or your index.
