the gist

T3 Code's Nightly build introduces Sidebar V2, replacing project-based nesting with a flat, inbox-style list that promotes active threads to rich cards and moves completed work to a compact 'Settled' section.

Transitioning to Inbox-Style Threading

The Sidebar V2 update fundamentally shifts T3 Code from a rigid, project-nested folder tree to a dynamic, flat list architecture. This design prioritizes active agentic workflows by rendering current threads as rich cards at the top of the sidebar, while relegating completed or inactive threads to a compact 'Settled' section. This approach prevents the visual clutter associated with long-running projects and allows developers to focus on immediate tasks without losing access to historical context.

Configuration and Workflow Management

Users can enable the feature by navigating to Settings, selecting the Beta section, and toggling the Sidebar V2 option. Once active, the system provides several mechanisms to manage thread state:

Auto-Settling: Threads without activity for a user-defined period (defaulting to 3 days) automatically move to the Settled section. Threads linked to merged or closed pull requests settle automatically regardless of the timer.
Manual Control: Users can manually settle threads via a hover action or snooze them using a built-in clock icon, which allows for temporary removal from the active view until a specific time (e.g., tomorrow at 9:00 AM).
Project Filtering and Search: A project filter dropdown at the top of the sidebar allows for instant isolation of threads by project. The Command-K search palette provides unified access to threads, commands, and projects, displaying metadata such as branch and project association for each result.
Rapid Thread Creation: The compose button triggers a project picker where each project is assigned a keyboard shortcut (e.g., Command-1), enabling high-speed thread initiation.

Settled Thread Behavior

Settled threads remain accessible as compact rows. If new activity occurs on a thread previously marked as settled, the system automatically promotes it back to the active card view. The Settled section itself is collapsible, and the interface intelligently hides older threads behind a 'Show More' button to maintain a clean UI footprint.
