Why not create a width tool like the one available in After Effects?
This would improve the freedom of creativity, and we would stop making characters with straight arms, geometric shapes, etc. I know that Animate CC exists, but the options offered by AE are infinitely better and easier than An. If you make an animation in AE, with figures created in AI, it is very noticeable that you have done with these two programs. We all have to do it in the same way, and that bothers me.
