Idea Tracking

I am using my own application to keep track of notes related to anything I feel important. For business related ideas new products, markets, partnership ideas)) I use the "Strategy" section. I have other modules where I can save notes like "Operations", "Marketing" etc..it all depends what type of ideas I get. From those ideas I can create "projects" as well. They are all consolidated in a central "Notes" page though so I don't miss something. It's a question of how much bandwidth I have to tackle them or not :)
