ChatGPT Atlas: Configurable Enter key behavior for IME users

Thank you, Smith. I appreciate you passing this along. The IME angle is the key point here: for Japanese, Chinese, Korean, and other composition-based input workflows, Enter is part of text composition before it is a send command. This becomes especially noticeable in Atlas side chat because users often write longer messages while referencing web pages, logs, code, or documents. A configurable send shortcut would reduce accidental sends and make Atlas much safer for IME users.
