Feature Request: Session rename and folder/tag grouping

Feature Request

Problem

As power users accumulate many sessions across multiple projects, the session sidebar becomes hard to navigate. Currently there is no way to rename or group sessions.

Requested Features

1. Rename sessions
Allow users to rename a session title after creation. The auto-generated title from the first message is often too generic (e.g., "Planner 3", "New session") and can't be changed later.

2. Folder or tag-based grouping
Allow users to organize sessions by project using folders, tags, or prefixes. For example:

• ABC: for ABC Supply AP sessions
• DBI: for DavidsBridal sessions
• PGP: for Sales & Marketing GTM sessions

This could be implemented as:

• Folders in the sidebar (drag sessions into project folders)
• Tags/labels that can be filtered
• Auto-prefix option in project settings (e.g., all sessions started in a directory get a prefix)

Current Workaround

Users must manually type a prefix in their first message to influence the auto-generated title, but this doesn't help with existing sessions.

Use Case

Users working across 5-10 projects end up with 30+ sessions that are hard to scan. Grouping by project would make it much faster to find and resume work.
