That's awesome! Thanks @lcobucci :-)

We'll review it soon and make sure to include it in 1.0.0.

@PROFeNoM Can you please have a look, at a glance it looks great to me, but maybe you have a comment?

[lcobucci]

Thanks, happy to help.

Do let me know if there's any change required 👍

[PROFeNoM]

Thanks for your contribution 😃 It looks very good to me. There would only be some minor, semantical changes to be made ,and then it's all good to me 👍

PS: Sorry for the delay reviewing, I was OOO last week ;-)

[PROFeNoM]
