Q: Panels have come apart or torn off into separate windows. How do I restore the previous layout?

Just close a torn-off window: the panel returns to its place in the dock. If the layout is messed up entirely, open “Settings”, the “Theme and colors” page, the “Panel layout” block, and press “Reset panel layout”: the panels of the current mode (MANUAL or AUTO) in all group windows go back to their default places at once, without “Save”. Settings, tables and windows that are already detached are not affected by this button; close those by hand.
