Message Level Editing Reordering And Insertion With Role Based Composition

via “message-level editing, reordering, and insertion with role-based composition”

Enhanced ChatGPT UI with folders, prompts, and cost tracking.

Unique: Provides fine-grained message-level control (edit, delete, reorder, insert) with support for all three OpenAI roles (user, assistant, system), allowing users to manually craft and test conversation flows without re-generating from scratch. Uses array mutations in Zustand for instant UI updates.

vs others: More powerful than ChatGPT's native UI (which only allows editing the last message) because it enables editing anywhere in the conversation and inserting custom assistant/system messages for testing.
