This sounds great, Konan! I can't imagine the work that must've gone into it. As Claude said above, if it works for Vue v.3, it should also work for v.4, so if you built it on v.3 specs those should also apply towards use with v.4. If built on v.4 specs, then there would likely need to be adjustments made for v.3 items. I'm not into animation myself, but there are many Vue users who are, and I'm sure they'll be glad to hear of this program! :)
