I was helping my dad turn on ssh on his Volumio and when we went to (volumio ip)/dev, it made me think. Would it be useful to be able to send commands to the Volumio through the url you use to access it? Something like:
192.168.0.7/<play playlist number 4>
You could bookmark that to your desktop and have one touch playing.
The GUI is simple and easy to use, but if I could set up something like that, my mom and my wife would both be more likely to use it.
