I'm not sure that there is. Bookmarks don't work as well because you can't preserve a session as easily. For example, I can just create a new tab group for a project that I want to work on, and then it will stay in the background until I have the resources to work on it. I don't know about other people, but I find it really useful to research a project and then leave it alone for a month or two before working on it. When I do this I often have a better perspective on the project than if I were to just jump in. With my setup, when I return to it my session is just as I left it; making it very easy to get up to speed.
