Hello
At the moment if the Details panel is tabbed (alongside the Scene Outliner say) and is not exposed, when you click the World Properties icon, you don’t see the Details panel displaying the World Properties because the other tab that’s exposed is “on top”. It would be a nice little grief reducer to auto-expose the Details tab when World Properties is pressed to avoid users getting all agitated. It might be nice to prompt the user, but I reckon probably just to do it will end up saving a click.
