   - **Package** - Named collection within a project
   - **Artifact** - Specific content instance identified by SHA256
 - **Tags** - Alias system for referencing artifacts by human-readable names (e.g., `v1.0.0`, `latest`, `stable`)
+- **Package Formats & Platforms** - Packages can be tagged with format (npm, pypi, docker, deb, rpm, etc.) and platform (linux, darwin, windows, etc.)
+- **Rich Package Metadata** - Package listings include aggregated stats (tag count, artifact count, total size, latest tag)
 - **S3-Compatible Backend** - Uses MinIO (or any S3-compatible storage) for artifact storage
 - **PostgreSQL Metadata** - Relational database for metadata, access control, and audit trails
 - **REST API** - Full HTTP API for all operations
-- **Web UI** - React-based interface for managing artifacts
+- **Web UI** - React-based interface for managing artifacts with:
+  - Hierarchical navigation (Projects → Packages → Tags/Artifacts)
+  - Search, sort, and filter capabilities on all list views
+  - URL-based state persistence for filters and pagination
+  - Keyboard navigation (Backspace to go up hierarchy)
+  - Copy-to-clipboard for artifact IDs
+  - Responsive design for mobile and desktop
 - **Docker Compose Setup** - Easy local development environment
 - **Helm Chart** - Kubernetes deployment with PostgreSQL, MinIO, and Redis subcharts
+- **Multipart Upload** - Automatic multipart upload for files larger than 100MB
+- **Resumable Uploads** - API for resumable uploads with part-by-part upload support
+- **Range Requests** - HTTP range request support for partial downloads
+- **Format-Specific Metadata** - Automatic extraction of metadata from package formats:
+  - `.deb` - Debian packages (name, version, architecture, maintainer)
+  - `.rpm` - RPM packages (name, version, release, architecture)
+  - `.tar.gz/.tgz` - Tarballs (name, version from filename)
+  - `.whl` - Python wheels (name, version, author)
+  - `.jar` - Java JARs (manifest info, Maven coordinates)
+  - `.zip` - ZIP files (file count, uncompressed size)
