First (and last?) sidebar I’ve made for Typo: a poll system. The code it’s at its early development but works. I started by a plugin, I found almost what I need then I wanted to integrate it to my Typo blog… It was more difficult to integrate this piece of code than to type it. And sadly I discovered that Typo is not really good to be extended, at least since you want more interaction between your sidebar with user than from a static page.
