You are completely right, I did not think enough about the "its", it was an easy way to avoid the his/her and I did not think it deep enough, but it was not a way at all to show less respect to the devs.
As far as the other mistakes are concerned, I corrected them, I wrote my post from my phone and the French auto correct did not help...
Thank you for your answer, I'll be sure to be more carefull in the future!
Cheers
