It looks like there is a bug in 2.0.50 that is stopping 'nam ify' from working. The following worked in 2.0.48 but not 2.0.50:
illuminator create
it to chord illuminator name ify
Also, there have been a few changes to Belcanto (e.g. kgroup disappearing and needing to be keygroup now) which is really frustrating and annoying - especially as its not reported in the Release Notes.
Any chance we could get a definitive list of the changes from 1.0+ to 2.0+ Belcanto ?
