使用场景 · Use case

When I quote a message, the quoted text lands in the chat box, but the input loses focus. I have to click back into the text field before I can type anything. This causes immense pain to me. I physically hurt.

建议方案 · Proposal

After a quote is inserted, the input should get focus automatically with the cursor at the end, so I can keep typing right away. Every major coding desktop app (Cursor, VS Code Copilot, etc.) already behaves this way.

预期价值 · Expected value

hundreds and hundreds times of switching back and forth between mouse and keyboard, thus losing momentum mid session

补充材料 · Additional context

No response

Begin with CONTRIBUTING.md, then locate the Windows desktop chat input and quote-handling entry points; the issue names no source files or tests. Done means that quoting a message restores focus to the input with the cursor at the end, allowing typing without another click.
