After months of hard work, we are happy to release the new feature: Outliner. We hope you love it! Here is how it looks when you are using outliner to organize bookmarks, annotations and notes.

Diigo is an awesome tool for collecting and organizing information you find on the Web. I found it when I was looking a way A) to annotate Web pages, and B) keep cached versions of Web pages.
Diigo Outliners are another tool for managing this content you might save. It’s sort of a dynamic outlining tool. It looks simple, but there is a lot of functionality. I’d like to start using it like Storify.
