Spot the new controls when you switch to Advanced mode
Turning on Advanced mode in Settings now shows you where the extra controls live, so you can see what changed instead of hunting for it.
Switching your user mode to Advanced in Settings turns on extra controls across the app. Until now nothing pointed them out, so you went back to your chat with no idea what had changed.
Advanced mode highlight
Pick "Advanced" in the user mode menu under Settings, then head back to a chat. The advanced icons in the prompt bar glow, and so do the advanced icons in the collapsed left nav, showing you where the new controls sit.
The glow fades on its own after a couple of seconds and shows once per switch, so it points you at the controls and then gets out of the way.
If you want the tour again, switch back to Regular and then to Advanced.
