The 2.0 version is simply amazing! Now it can export the animated-textures that uses multiple rows setup, such as numx 4 numy 4, whilst the former chokes on it and only works with single line animation such as numx 16 numy 1. Other than that, I do also think the updated version runs much faster than its predecessor. Hard to tell a difference of the end-result but I think the quality of the exported goods is much pleasing to the eye now.
TL;DR - a must haves to improve your game/mod's QoL!
