HI,
I'd like to hear your thoughts on where is the best place for a manager or indidividual to take personal notes, on ideas, or things to do, or things to talk about with other people. they are not tasks, but a place to take daily active notes, that sohuld be private. ideally, people look at these notes daily, and then start to turn them into action items.

is there plugin, or a preffered place for doing this? thanks
