Roadmap for Fret/Fretish development?

[dbahu]

I am a new user to Fret - and it seems to me to be a powerful and important tool.
I would like to understand is there is a roadmap for the further development of Fret and in particular the Fretish language to be more flexible - for example including the possibility of sets of components and the existential operators for all and exists?

Thanks for you time and patience!
