There is no way to change the default line spacing of 1.2 to a more useful 1 (single spacing).
Adobe's default line spacing is set to 1.20, which is uncommon in documents. Single spacing (1.0) would be much more useful. Because I can't change the default, I have to continually change the line spacing from 1.2 to 1, which is annoying and time consuming. Please update the software so that the user can select the default line spacing.
