1 – Problem Statement
- In long technical threads, user-side “prompt panes” (our questions / code blocks / screen-shots) often grow to 100 k–200 k tokens.
- Scrolling becomes slow and visually noisy.
- Readers who return later mainly need the assistant’s answers, not every historical prompt in full.
2 – Feature Request: Collapsible Prompt Panes
Add a UI control that lets each user message collapse into a one-line stub (timestamp + first 60 chars).
- Default state: collapsed for messages above N screen-heights old (e.g. > 3 pages).
- Toggle: click or press ▸ to expand / ▾ to hide.
- Bulk actions: “Collapse all prompts”, “Expand visible prompt”.
