A friend passed me a link to a nifty app that can be of great help when it comes to remembering setups, instrument placement, settings or whatever. It's basically a tool to help you remember multiple actions. You can make a chain that can consist of text, audio recordings, pictures, videos etc etc. You can view the entire chain like a slide show.
It's nice that you don't have to draw things out for yourself but the best is that you can share what you made. So if your friend/college wants to use that super-fat-sound you made, you share your chain with him :)
