Support assistant across all tabs: global panel (title bar button and in terminal, Docker, firewall and network tabs) that uses the active tab as context (terminal output, container/stack view, compose editor with masked .env values, firewall rules, network config); chats are stored in the vault and can be switched, started anew and deleted; stop button while answering
