Hey @TheChris,
add this setting to user settings JSON:
“workbench.sideBar.location”: “right”,
This is working for me!
Is it possible that something has been overridden in this pane?
On any new window, it should match what you have set in your JSON. If you have workbench.sideBar.location set to right, the Agent Sidebar option will be set to left, and vice versa.
