Anthropic has redesigned the Claude Code desktop app to integrate full terminal and file system agency into a polished user interface, prompting many users to switch away from Cowork0:38. While Cowork formerly offered a simpler UI, the new Claude Code layout brings feature parity and beyond, adding a dynamic progress to-do list1:34 that updates live as Claude completes tasks, along with environment, context usage, connectors, and outputs side cards. Furthermore, users can now group chats into custom sections2:27 and trigger automatic context compaction2:04 when approaching token boundaries.
The most substantial architectural upgrade introduces projects and nested sessions2:52. Instead of juggling disconnected chats or overloading a single conversation's context window, users can appoint an orchestrator agent that spawns dedicated child sessions for subtasks like drafting, outlines, and visuals. These nested sessions iterate independently4:21 without context spillover while reporting progress back to the central coordinator. While Pro and Max tiers gain access to cloud-enabled projects with shared memory, team workspaces use locally executed nested sessions6:01 with structured briefs.
To streamline complex workflows, Claude Code introduces persistent side chats6:44 that replace the ephemeral `/btw` command. These side windows can inspect the primary chat's history, check task timelines, and even transmit instructions back to the main thread without bloating the primary context window. For parallel execution, the new split view multitasking7:48 enables dragging multiple conversations onto a single screen to monitor separate tasks simultaneously.
Claude has also expanded its native office suite inside artifacts, featuring live connector-fed dashboards8:50, downloadable presentation decks in Claude Slides9:08, real-time collaborative Claude Docs9:17, Figma-style wireframing in Claude Design9:24, and code-driven animation with Claude Motion9:45. To optimize token efficiency, new slash commands like `/doctor`10:50 scan prompt files for deprecated instructions, `/skill-doctor`11:26 unloads unused tools to reclaim tens of thousands of tokens, and `/advisor`11:56 delegates critical decisions from cheaper models like Sonnet to Opus. Finally, the newly introduced Claude Code mods12:24 allow users to customize UI and input behavior, such as automatically converting rambling voice transcripts into structured prompt briefs.
