Learnmeabitcoin's developer [Greg Walker] recently launched the second version of this explorer
Thank you for this heads-up, SFR10! At same time, I have to apologize for the delay in replying you here. I've been extremely caught recently and, to be honest, I forgot to reply...
Regarding this explorer, indeed, it looks like we have a rebranded version. Do you think it should be added to OP...? It's first version was rated with 5/10, which is not a very good mark... In any case, it was added since it was proposed by ajiz138 and also rated by him. If you believe this explorer should be added, are you so kind, please, to rate it in the format from the table from the bottom of OP?
BTW, am I correct in assuming that "3xpl" hasn't been added to the list due to not having a rating up to this point, or is it something else? 
Regarding this explorer, as far as I see, Bitcoin_Arena said he can't rate it and since then nobody did it... If you look at 1miau's post (just next to the one you linked), he told Bitcoin_Arena to wait until someone would rate this explorer, in order to have some information about it but, since then, nobody did it... This is why it was not added to OP yet...
