[FEATURE] Session grouping / labels in the claude code left panel

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

Currently, sessions in the left panel are listed chronologically with no way to organize them. As the number of sessions grows, it becomes hard to find and manage related ones.

Proposed Solution

Add the ability to group sessions into user-defined labels or folders in the left panel — similar to how chat apps (Slack, Discord) or browser tab managers let you organize conversations into categories.

Right-click a session → "Add to group" or "Move to group"
Create a named group (e.g., "Work", "Personal", "Research")
Groups appear as collapsible sections in the left panel
A session can belong to one group; ungrouped sessions stay at the top or bottom as "Uncategorized"
Why it's useful:

Users with many sessions across different projects/contexts have no way to visually separate them
Grouping reduces time spent scrolling/searching for a specific session
Makes Claude Code more usable as a daily driver for people juggling multiple ongoing workstreams

Alternative Solutions

Manual session renaming with prefixes (e.g., [Work] ...) works as a workaround but is tedious and provides no actual UI separation.
