ChromeIdea is an extension for your browser that lets you manage a project with your friends or website's visitors, making it an excellent pool for collecting or throwing around ideas.

Why install it?

If you are part of a group of friends, colleagues, or family members that are interested in the same thing, you can create a new project, install the extension, and ask them to also install it. You now have a convenient forum for your group, or a small bug-tracker system, or even a way to create a to-do list.
