Chat UX: queued message lost on interrupt, no immediate-send shortcut, and ESC behavior differs from Claude Code

[icoe44]

Summary

Three related UX issues with the chat input / message sending behavior in the Codepilot desktop client:

1. Queued message lost on interrupt: When the user types a message while the model is still generating (message is queued), then presses ESC or clicks stop to interrupt the current generation, the queued message is silently discarded instead of being sent.

2. No immediate-send (interrupt + send) shortcut: In Claude Code CLI, Ctrl+Enter sends the message and immediately interrupts the current generation. In Codepilot, there appears to be no equivalent — the user can only queue messages, and there's no way to force-send with immediate interruption.

3. No interrupt-and-send button: Unlike Cursor (which has a visible "send anyway / interrupt" button that appears when you type during generation), Codepilot only shows a "cancel" action for queued messages, but no way to promote a queued message to an immediate interrupt-and-send.

Detailed description

1. Queued message lost on interrupt

Steps to reproduce:

1. Model is generating a response
2. User starts typing a new message in the input box (message is queued, shown as pending)
3. User presses ESC or clicks stop to interrupt the current generation
4. The queued message disappears without being sent

Expected behavior:

• Pressing ESC while a message is queued should: interrupt the current generation AND send the queued message (matching Claude Code CLI behavior)
• OR at minimum, the typed text should be preserved in the input box so the user can re-send it manually

Actual behavior:

• The queued message is silently discarded. The user cannot recover the text they typed — it's not preserved in the input box, not in clipboard, not in any history.

2. No immediate-send shortcut

Expected behavior (from Claude Code CLI):

• Enter → queue the message (send after current generation completes)
• Ctrl+Enter → immediately interrupt current generation and send the message

Actual behavior in Codepilot:

• Enter queues the message (works)
• Ctrl+Enter behavior is unclear or non-functional as an interrupt-and-send
• No visible keyboard shortcut hint for immediate send

3. No interrupt-and-send affordance

Expected behavior (from Cursor):

• When user types while generation is active, a visible button appears: "Send anyway" / "Interrupt and send"
• This gives the user a clear choice: queue or force-send

Actual behavior in Codepilot:

• Only a "cancel queue" option is shown
• No way to promote queued text to an immediate send

Suggested improvements

1. ESC behavior: Match Claude Code CLI — ESC interrupts generation AND sends the queued message
2. Ctrl+Enter: Implement as immediate interrupt + send
3. Queued message preservation: Even if not auto-sent on interrupt, the typed text should be preserved in the input box (not discarded)
4. Visual affordance: Consider adding an "Interrupt and send" button that appears when the user types during generation (similar to Cursor's pattern)

Related UX principle

The current behavior creates a frustrating loop:

1. User types a correction/follow-up while model is generating
2. User interrupts the generation (expecting their queued message to go through)
3. Message is silently discarded
4. User has to retype everything from memory

This is particularly painful for long or carefully crafted messages.

补充复现信息（按 issue template 要求）：

版本号: v0.64.0
操作系统: Windows 11 Pro 10.0.22621
Runtime: codepilot_runtime（桌面客户端）
Provider / 模型: 无关，纯前端 UI 行为

复现步骤（排队消息丢失）:

1. 模型正在生成回复时，在输入框输入一段文字
2. 观察到输入框显示为"排队中"状态
3. 按 ESC 或点击停止按钮打断当前生成
4. 观察：排队消息消失，输入框清空，无法找回已输入的文字

预期行为（参考 Claude Code CLI）:

• Claude Code CLI 中，ESC 打断当前生成的同时，会将排队中的消息自动发出
• 或至少保留已输入的文字在输入框中，不丢失

预期行为（参考 Cursor）:

• Cursor 在用户输入时显示"Interrupt and send"按钮，用户可以明确选择是排队还是打断并发送
