Not hard, of course, but in the Blogger of the Beta it doesn't work. Beta Help says that "in your published blog, all <b:section></b:section> and <b:widget></b:widget> tags will be replaced with <div></div> tags, which will have the specified ID. So you are welcome to refer to, for example,
div.myListin your CSS if you want to."
Long & short of it.... View source is no longer going to reflect cut & pasteable examples of features that you want to add.
Might I also propose a "beta code" category on the wiki for swapping & sharing beta widgets?
