i just made a simple Coda doc called IdeasKeeper. It inspired by James Altucher idea machine (writting 10 ideas a day).
Im using paper notebook but after a while it gets pretty messy and I couldnt keep track on my ideas so I made the document in Coda :).
I made a video where I describe it a little bit
Hope you like it.
If you be interested I can share the doc with you, just let me know (need to get rid of my data first hehe)
Would be happy to hear any feedback.
