There is no option to multi login on same contanier, like 1 gmail account to personal and another for work...
It's a very nice idea of thw extension, but is missing a few useful functions that you can only have on google chrome like this one I said.
Another thing is that even if you add any adress to your container and when you try to open it with your saved favorites adresses,you will have to save again site bye site to when you open it form your favorite bookmarks, it load on the exactly container that you want, otherwise it never open on the correct tab that you configured.
