I would be great to be able to control different channels/strips, with different arduinos (or even one, i don't know if it's possible). You could do 2 different effects from the same program.
It would also be great to add support for non-adressable RGB strips that would match with the adressable effect (don't know if you followed me there :p). I personnally have rgb fans (non-adressable) and this would be a nice feature
These are just ideas, i don't even know if its possible.
Keep up the good work and again, thanks for helping the community
