Curve Tool and Pen/Pencil Stabilizer

I love the Philosophy of pencil2d being a straight up simple traditional style animation program. I do however feel that if you add a pencil stablilizer similar to sai, It’ll make lineart process and even drawing easier. As well as a curve tool similar to sai or retas. So far I can only do my rough animations here and I have to export the png sequence to another program. Itll be great if the lineart would be beefed up here so i can do it all in 1 program rather then exporting and lining/coloring elsewhere
