I've been playing for years, and so happy to see an app so intuitive. The only thing is that I use several non standard tunings none of them are found in the drop down..... I was so looking to put my own custom tunings into this app, since its the best designed guitar app that I've seen in a while. I would love to use this over OOlimo (which allows your own tunings) I'll have to wait and see if this is actually a feature you would consider here. Thanks for sharing, it's great!
