It's been a long time we could not find the time to work on this, and really, the implementation of the old architecture work 'good enough' for most our daily needs.

I believe there are a lot of good ideas and wonderfull design in butter that we wish would get to life, but we have to be honest to ourselves: we will probably not be the ones that will push it through anymore.

Cheers, and thanks for all the fish.


This in butter-next-gen ! based on react, redux and electron !
