It's quite useful when one is doing Internet researches! I've just started using it in my searching for a html beautifier SDK for LIVEditor (my live html/css code editor).
Would you consider adding a 'Notes' section, just like 'Tasks'?
One of the main ideas for future direction is to integrate it more with existing services for Todos (RememberTheMilk, etc.), Notes (Evernote, etc.), instead of rebuilding those tools.
So, imagine having an Evernote notebook for a project, and managing all notes from it on the homepage. That way your information is still in the cloud, in the service of your choice, but accessible within the context of a project.
