Hello,

@MyHoldFast Please Add support for:

1. using a single set of credentials while maintaining cookies/sessions.
2. using proxies where switching/restarting a proxy forces a new session/cookie.
3. model selection features (choose other DuckAI models, set system prompt) including image uploads for multimodal models (e.g. GPT-4o mini).
