This is annoying. It's arbitrary (why not 12? Why not 112? Why not 8?) Hell, while we're changing defaults, why not set all fonts to be bolded, and if you complain, someone will tell you "Change it in the prefs"!
I know I could change it in the preferences or in the normal template, but
the user should not have to change an unasked-for behavior in order to set it back to the way it should be. When I want something single-spaced, I want it single-spaced throughout the document, not single-spaced throughout the document EXCEPT after paragraph returns, because, MARTIN and his evil minions believe those are special places, and they clearly think that the paragraph indentation just isn't quite enough to indicate that a new paragraph has begun, so they're SUPPLEMENTING a perfectly good paragraph indentation with EXTRA SPACING AFTER THE PARAGRAPH THAT I DIDN'T TELL THE APP TO DO.

GRRR!!! HULK SMASH!!
