Hi,
Here is another update - v0.1.6.
This one has a small functionality change in that it prevents you from reducing a menu value to below zero. This caused "ERROR" to be displayed, so this version is a little more robust.
There is also a small non-functional change to the argument formats used to call a parent class method.
The source code has been reformatted with the Arduino IDE (version 1.6.

so there will be loads of changes if you do a file compare. If you are keen to know what has changed, clone the code from Github and look at the commit before the current level.
Again, enjoy and please let me know if there are any issues.
Cheers
Frantech
