Amber - Simple Markdown

- Document changes are recorded as previous versions on the current device when the document is saved. - View the full text of a selected version and compare it with the current document. - Long unchanged sections are collapsed and can be expanded whenever needed. - Restoring a version preserves the current content as a pre-restore version when necessary. - Version history is stored only on the current device, not in iCloud. - Check history storage usage in Settings and choose a limit from 5 MB to 1 GB. - Older history is compacted into representative minute, hour, and day versions. When the limit is reached, the oldest versions are removed first. - Expanded the built-in tutorials to nine documents per language, with more guidance for heading navigation, search, version recovery, Trash, and Settings. - Refined recently added interface text in Korean, English, Japanese, and Russian.
