Second, I can't figure out a way to save a layout to play with but not actually apply it to my journal yet, the way you could with S1. This strikes me as a huge problem.
Third: the "History and Motivation" page says, "The four views (recent ("lastn"), friends, calendar, and day) all had to be created independently and couldn't share any code. So if you wanted to make a new style you had to do it four times. [...] S2 addresses all these problems." Honestly? I don't want all my views to be the same. I can deal with a layout like the "3 column" one for a main [recent/lastn] view, but for the flist view frexample it feels very cluttered. Plus of course I have lingering bitterness that the default is to force your S2 view on your comments pages. But the real problem is that I don't want it to force all the stuff I would like on the main view (header image, links column) onto the other views.
