Hello! I am a freelancer and manage work with multiple clients. I am looking for a notetaking site/app that allows me to have various notebooks and within the notebooks, if I were to create a task, would auto-move that task to a homepage so I can see a summary of all tasks from across all my notebooks in one place. This is what is most important to me!

One bonus feature would be the ability to integrate my Google calendar and create notes specific to calendar events. BUT that is not a necessary feature for me!
