Thank you very much for the PR. The only required change is to avoid multiple validation of the same dataset, all others are nitpicks you can ignore.

[Galileo-Galilei]

Thank you for the update. There is only the double validation check to perform and it's good to go!

[Galileo-Galilei]

Thank you for everything, it's merged!
