I took a cue from Celody Life and added a similar opening tutorial. This is a much better alternative to the awkward "Start Menu" I added in the last NanoTone Synth update. 

Now everything is on one page again - though you can still view the longer tutorial by clicking the ? button or pressing the L key.

I think about improving the GUI or adding more comparison features now and then, but I think I could call this finished as it is. I'm glad to know it's been helpful to people. ^_^
