From 43b63ccae89cf911c1d3fecc4577a98b898d6048 Mon Sep 17 00:00:00 2001 From: Jeremy Rose <172423086+nornagon-openai@users.noreply.github.com> Date: Fri, 26 Sep 2025 16:35:56 -0700 Subject: [PATCH] update composer + user message styling (#4240) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Changes: - the composer and user messages now have a colored background that stretches the entire width of the terminal. - the prompt character was changed from a cyan `▌` to a bold `›`. - the "working" shimmer now follows the "dark gray" color of the terminal, better matching the terminal's color scheme | Terminal + Background | Screenshot | |------------------------------|------------| | iTerm with dark bg | Screenshot 2025-09-25 at 11 44 52 AM | | iTerm
