Goal: analyze and pilot this coding release update in my project.

Context

Assistant: Windsurf Proposal: Set devin.agentWindow.location to split Agent Command Center into its own window Summary: Windsurf v3.8.20 Agent Command Center follows the selected space, converts an editor in place, and supports any number of side-by-side agent windows. Set devin.agentWindow.location to detach it, trust workspaces for local agents, and review Devin Local Markdown plans before Implement. Primary source: https://windsurf.com/changelog#v3-8-20

Why it matters

v3.8.20 unties the Agent Command Center from a single folder so it tracks the selected space, converts the current editor window in place with no reload or save prompt, and lets any number of agent windows run side by side. The new devin.agentWindow.location setting splits the command center into a separate window from the editor, and Ctrl/Cmd+G Agent/Editor switching is significantly faster—detach the center, keep multiple agent sessions visible, and treat mode switches as cheap. Untrusted workspaces now warn in the sidebar, composer, and welcome page and offer a trust prompt required to activate local agents. Devin Local plan mode emits a full Markdown plan you can review independently, with an explicit Implement button, and running subagents can be stopped individually without cancelling the turn. Session rename from the tab dropdown, multi-root workspaces with virtual filesystem folders, Current Workspace conversation filtering, and post_setup_worktree hooks that copy .env and untracked setup into Devin Local worktrees complete the workflow; Windows Desktop updates now refresh the bundled devin CLI via a shim.

Suggested actions

1. In Windsurf/Devin Desktop settings, set devin.agentWindow.location so the Agent Command Center opens in a separate window from the editor. Then open additional agent windows and switch spaces: the center follows the selected space instead of staying tied to one folder, and any number of agent windows can run side by side.
2. Convert the current editor window in place to Agent Command Center (v3.8.20 does this with no reload and no save prompt). Use Ctrl+G (Windows/Linux) or Cmd+G (macOS) to switch Agent and Editor mode now that switching is significantly faster.
3. If the agent sidebar, composer, or welcome page warns that the workspace is untrusted, accept the trust workspace prompt so local agents can activate.
4. In Devin Local plan mode, review the full Markdown plan file separately, then click Implement. Stop individual running subagents without cancelling the turn.
5. Rename the current session from the tab dropdown. For Devin Local sessions that create worktrees, keep post_setup_worktree hooks so .env files and other untracked setup are copied in before the session starts; use multi-root workspaces that contain virtual filesystem folders when that matches your repo layout.
