 ## 🌟 Features
 
-- **Model Flexibility**: Choose from hundreds of OpenRouter-supported models (e.g., GPT-4, Claude, Gemini) with substring-based search and selection [github.com](https://github.com/owengretzinger/gitreadme) for template-inspired ease.
-- **File Attachments**: Attach images (JPEG, PNG) or plain text files directly to messages using `@path` syntax, with automatic Base64 encoding for models that support modalities.
-- **Streaming Responses**: Enable real-time streaming for faster, live responses; toggle on/off via config commands (inspired by streaming in modern chat apps).
-- **Persistent Configuration**: Securely store API keys, base URLs, and settings in a local SQLite database for reuse across sessions.
-- **Rich UI in CLI**: Enhanced console output with Rich library panels, tables, and progress indicators for a polished terminal experience.
+- **Model Flexibility**: Choose from hundreds of OpenRouter-supported models (e.g., GPT-4, Claude, Gemini) with substring-based search and selection—inspired by dynamic model retrieval in advanced CLIs [github.com](https://github.com/oop7/OrChat) for seamless user experience.
+- **File Attachments**: Attach images (JPEG, PNG) or plain text files directly to messages using `@path` syntax, with automatic Base64 encoding for models that support modalities [github.com](https://github.com/rdhillbb/openRchat), enhancing multimodal interactions like in OrChat's smart picker.
+- **Streaming Responses**: Enable real-time streaming for faster, live responses; toggle on/off via config commands (inspired by streaming in modern chat apps), with Ctrl+C cancellation support similar to advanced TUIs.
+- **Persistent Configuration**: Securely store API keys, base URLs, and settings in a local SQLite database for reuse across sessions, leveraging cross-session persistence like in OrChat's conversation management [github.com](https://github.com/oop7/OrChat).
+- **Rich UI in CLI**: Enhanced console output with Rich library panels, tables, and progress indicators for a polished terminal experience, drawing from Ink-based interfaces in React TUIs [github.com](https://github.com/rdhillbb/openRchat).
+- **Arrow Key History Navigation**: Scroll through previous user inputs using up/down arrow keys for quick recall and editing, akin to command history in shells and CLIs like those using prompt_toolkit [prompt-toolkit.readthedocs.io](https://python-prompt-toolkit.readthedocs.io/en/stable/pages/tutorials/repl.html), for efficient iterative chatting.
+- **Screen Clearing**: Instantly clear the terminal screen with the `/clear` command, maintaining session state while providing a fresh interface—similar to `/cls` or `/clear-screen` in advanced chat apps [github.com](https://github.com/oop7/OrChat), preventing visual clutter.
 - **Clipboard Integration**: Copy AI responses to the clipboard with a single prompt.
 - **Help Command**: Built-in `/help` with examples for all commands, making the app self-documenting and user-friendly [github.com](https://github.com/Piyush64-bit/ReadMe-Generator).
 - **Error Handling**: Graceful prompts for missing configs, file issues, and model incompatibilities.

 - **Streaming**: Enabled by default for live responses; press Ctrl+C mid-stream to cancel (supported by most providers).
 - **File Limits**: Max 10MB per file; only images for vision models, plain text otherwise. Supports `@~/relative/path` or absolute paths.
+- **Arrow Key History**: Sessions retains a history per run (resets on exit), allowing quick re-use or modification of inputs for iterative conversations.
 - **Error Recovery**: If no models fetch initially, check your API key. Prompts guide you through setup.

 - **No Models Available?** Ensure your API key is valid and has access to models [openrouter.ai](https://openrouter.ai/docs/api-keys). Check network connectivity.
 - **Streaming Issues?** Some models/providers may fall back to non-streaming. Toggle with `/config stream off`.
 - **File Attachment Errors?** Confirm paths are absolute (e.g., `@/home/user/file.png`) and files are under 10MB. Unsupported MIME types will be rejected.
+- **Arrow Key Issues?** Ensure `prompt_toolkit` is installed; arrow keys work in supported terminals (TTY environments). Falls back gracefully in non-interactive modes.
+- **Clear Screen Fails?** ANSI escape sequences are used cross-platform [usavps.com](https://usavps.com/blog/46203/), but may fall back to newlines in rare cases.
 - **API Errors?** Re-set your key or check model compatibility (e.g., vision models for images).
 - **Permission Denied?** Ensure the app has read access to attached files and the database directory.
