@stevengj help appreciated… and post sent: many thanks 
it is actually nice to be sync with JuliaCon Paris this thursday where we have two talks related to the package
cheers
ps. @goerz reminds me of JuliaCon 2023 when, if i’m not mistaken, you were the one validating the first release of OptimalControl.jl on the general registry, just a few days before the conference
