Feature description:

Hello, cordial greetings. I know that dreaming costs nothing and programming costs a lot. However, I put this idea to your consideration. The algorithm could remove or create nodes depending on what is drawn on the next frame in the timeline.

I attach a gif where I recreate how it could work.

Thank you very much for your attention and for your excellent work.

It could also work in the following way:

1. selecting some vertices

2. Drawing the shape you want the vertices to have in the next frame.
