Three years and /copylayout is still not working, it's actually worse than it was because now it doesn't copy the chat tabs. https://dgcissuetracker.com/browse/EQ-1182
It copies windows but man it would be awesome if it copied filters too, and opened those windows, and had an option to reopen a window # once closed.
Colors are, and show settings, but filter1->window3, filter28->window7 etc. is stored per character and is NOT copied when copying layout, which makes the command mostly worthless for most people.
