How to keep track of side projects and product ideas I'm validating?

How do you keep track of and organize your projects? I'd like some sort of a project dashboard for each were I have links to everything regarding that project, like promotional posts I've made, feedback I've received, link to project repo(s), link to to-do board, link to analytics page, etc.

Even when I'm working only on one project I kind of get this constant background anxiety that I've forgotten to check up on something and I'll obsessively open up reddit, IH, etc to check if I have notifications I've missed.

Is there something out there that can help? Or is it just me?
