v2.1.231**Bug Description** Claudea a une façon de s'expirmer en français qui est très mauvaise. Il utilise plein de métaphores alambiquées, complexes et pas du tout dans d'usage dans le langage commun. Ensuite il a tendance à ne pas utiliser pas les bons mots pour les bonnes choses et a parler d'une façon très complexe la ou on pourrait utiliser des mots simples. c

## Problem When several Claude Code CLI sessions run in parallel (e.g. one session per ticket) and each uses Claude in Chrome, every session gets its own Chrome tab group, but all of the groups are titled "Claude" and differ only by color. With 4+ concurrent sessions, often holding visually identical tabs of the same local app, there is no way to tell which

### Summary In a remote-control session, clicking a file link in the chat never opens the file in the side panel.

When running Claude Code in a terminal, it would help to have the tab title reflect the current working directory (or at least the last path segment).
