Choosing Web vs. Desktop console mode
Settings → General → Connector & Console Mode picks how a double-clicked node opens: Web console (default - everything runs in the browser tab, nothing to install) or Desktop console (hands off to the local Connector app for a native terminal/Wireshark/VNC/RDP window instead).
Toggling to Desktop console takes effect immediately - the next console you open hands off to the Connector instead of opening in-tab.

No admin needed - every account controls its own console mode. See "The Connector" for what Desktop console mode actually installs.
