Problem Statement

When using a side chat (the read-only auxiliary window) inside Claude Code to discuss a project with Claude, I asked it to apply some code edits directly. Claude replied that this window is read-only and suggested I manually copy and paste the generated changes into the main conversation myself.

It would be helpful if the side chat could apply changes directly to the main conversation, or at least offer a one-click way to send the generated result there, instead of requiring the user to manually copy and paste the content between the two windows.

Proposed Solution

Add the ability for the side chat to push its generated changes into the main conversation, either by applying them directly or via a one-click "send to main conversation" action, removing the need to manually copy and paste the content between the two windows.
