So much for separating content from presentation..

I changed my blog template and it is not painless. All the changes that you have made in your earlier template are lost. So I had to redo the blogroll integration from bloglines. I was also faced with redoing the haloscan comment integration but now blogger provides comments so I skipped that one. Why don't I get to choose/edit a css separately from the blog content template? Blogger people must have surely thought about this..what am I missing?
