merge all windows default

[robberlost1]

is there a way to make the 'merge all windows' option on mac book pro an automatic default, so it will perform this function whenever a new window is opened up ? I don't want to have to choose this option 'each time' I want a to merge all windows

Which "Merge all windows" command do you mean and where exactly does one find it?
