Soggy bottom. Skim the top, leave the rest on the tray.
Summary
A developer describes switching from IDEs to Claude Code sessions in macOS Terminal in early 2026, running multiple sessions simultaneously. This created confusion because all terminal windows looked identical, making it impossible to distinguish between different agent sessions and leading to giving wrong instructions to the wrong agent. The article introduces Mantel, a lightweight macOS terminal solution that adds per-project colors, icons, and names to help users differentiate between multiple terminal windows when running Claude Code sessions.
Key quotes
· 3 pulledWith the regular terminal I was constantly cmd-tabbing into the wrong window and giving the wrong agent the wrong instructions, because literally every terminal window and every project looked EXACTLY THE SAME.
A slim terminal window just seemed more lightweight to me than 4 full-blown IDEs.
Works and feels just like your normal terminal, but you can actually tell your windows apart and don't lose your sanity.
