Dock the composer beside the thread for long prompts

[akiva-quickvett]

This is a proposal for a full-height composer you can dock beside the thread, for writing long prompts.

I find when I am writing longer prompts, defining a lot of specs, its nice to have an editor that is pleasant to use instead of the normal chatbox.

I give you the super-prompt editor.

1. Dock the composer beside the thread

Cmd+Shift+Enter / Ctrl+Shift+Enter moves the composer into a full-height editor beside the conversation.

• The thread keeps its width, so you can read it while you write. The editor takes the spare space in the workspace.
  • It only docks when there's room for both. If the window gets too narrow, it goes back to the bottom, and docks again once there's room, until you send.
• In the docked editor, Enter adds lines. Cmd+Shift+Enter sends and returns the composer to the bottom.
• Once a prompt grows past a few lines, a button beside Send docks it too, for mouse users.
• Drag the editor's left edge to widen it for the session. Double-click the edge to reset it.

2. Ask while you prompt

This is something I found myself reaching for when I'm writing a super prompt within a thread. Is needing to ask aside questions, or do a quick task while im writing something. also making it easier for to cite something I the super-prompt.

Scope

• Web and desktop, through the shared web client. No server, contract, provider or RPC changes.
• Mobile is unchanged.

Both parts are working and tested. My version of it isn't exactly 100%.

Vision

I could imagine adding better support for super prompt drafting or improving the editor features for the composer especially in the fullscreen view.
I imagine there may be value in also persisting these kinds of prompts, so the user can distill them into skills if needed.
In general the direction I find LLMs going is that quality human input is the most valuable commodity in the AI world, so building around making quality and powerful inputs, allowing a person to write without friction.
