- ls: compact view with status dots and folder markers
- ls -la: table view with status, lang, date, title; folders show mini status bar
- tree: recursive hierarchy using Spectre.Console Tree widget, context-aware
- All commands: CancellationToken threaded through ExecuteAsync
- Partition() helper respects topic-relative slug depth
- Startup banner: FigletText + capabilities panel + note stats with status dots
- JSON cache at ~/.cache/noz/notes.json for instant startup
- Cache-first loading: show REPL immediately, refresh notes in background
- Timestamp in stats line (e.g. 'vor 5 Min.') for data freshness feedback
- Ctrl+C in idle exits REPL gracefully; during command cancels only the request
- Per-command CancellationTokenSource so cancel does not kill the session
- Tab completion: command-aware (cd only suggests folders)
- Replace flat path string with CurrentTopic + CurrentSubPath
- SlugRelative() strips topic prefix for relative name resolution
- FoldersInView() returns topics at root, slug sub-segments within topic
- NotesInView() filters by topic and subpath
- NavigateTo() / NavigateUp() for cd navigation
- ResolveSlug() / ResolveNewSlug() for command argument resolution
