Go to your home node (in user settings) and turn on your 'personal nodelet' node. It will allow you to add different nodes - AKA 'bookmark.' The only part that I find a bit frustrating is that you can not organize (re-order) them. They are in the order that you add them.
s/node=/node_id=/. Using node= will usually work but node_id= will be faster and is immune to being "tricked" by nodes having a title that is equal to some other node's number.
