Yep, same thing for me, I've started using Vis in French at first and then switched to English because it's more convenient for fonctions (Imagine the HTML tags in your own language, kind of weird no? ).
But what would be really useful is new video tutorials (I mean, covering new stuff of Vis. Like "How to export the game ?", "How LUA is working ?", or "What not to do in Visionaire ?" for exemple) hosted on YouTube and then subtitled in other languages (I could translate in french). Even maybe weekly little tutorials, that would be awesome !
Sorry I know it's not the topic's subject but I get the point of Laxotine. Most of us (Vis users) reads english, but I think we mostly need to understand the way that Vis is working, and it's more understandable when it's translated. I can translate the existing tutorials of "GlenFX" but it could be way better if it was a series of tutorial videos !
What do you think guys ?
