I'm happy to spend a little extra time every now and then doing some unusual task by hand in exchange for never having to think about the editor or try to remember how some powerful, infrequently-used feature works. As long as the editor can do everything I want to do on a daily basis, I'm happy; if it can also automate tasks I only have to do every week or two or every couple of months, it's a waste, because it'll take some effort to remember that the feature exists, what it's called, where to find it, and how to use it. I'd rather just use a simpler editor and deal with that oddball task in whatever way is convenient when it comes up. Since I spend all day slinging code, bashing up a little script to do some odd code-munging job is no trouble; I already have all the tools I need to do that paged into my working memory.

I was thinking more of the sorts of automatic refactoring tools some people really like to use in their IDEs. I haven't found that such tools save enough time to be worth learning how to use them.
