I talk to my friend that introduce me to the tool and he gave me the website where he got it from.
Here it is:
http://max.slid.free.fr/maxEscapeCreation/eng/requiredTools.phpI actually know the creator of this tool, he makes slide maps. One well known map he created is "Murloc Slide".
Not much info on the tool itself though. I'm pretty sure he made it because I can't find the tool anywhere else but I could be wrong anyways that is all the info I have. I have to get in contact with Maximaxou to make sure but we are in different time zones and I hardly get on wc3 anymore so its kinda hard to get a hold of him, hes a Europe player.
-Edit
Just notice he has forums on that website so might end up making an account to get some info.
