### Added

- Choose a data directory in Settings → General → Data Management. Migrate to an empty folder on the next launch, preserve the original data as a backup, and keep using the original directory if copying fails. Retain command-line/environment overrides for desktop and server deployments. (#673, #1204)
- Select XPath fields in an isolated preview with original page styles and images, hover highlights, ancestor selection and extracted samples. Start from an article title to suggest a list and infer its links; calibrate the list or any field with a second example, review highlighted matches and field coverage, and retain manual selection. Disable source scripts, forms and navigation. (#1205)

Cache eight recently opened article bodies while preserving cancellation and invalidation behavior. (#771) (@expoli)
- Window long ungrouped normal/compact article lists. Keep cards, tables and grouped
