Yo who remembers Framecast?

If I remembered correctly framecast shutted down in like 2020 or 2021. That was one of my favorite animation app before AnimeMaker and Folioscope. I think I used to only animate transition cuts that looked cool. It was black bars that moved a lot. I was named PLANK there or something, it was inspired by a meme of a plane tank called “plank” lol.
