The auto cutting tends to leave tiny little pieces of curves sitting around. I am constantly confusing dust on my screen for small curves, and small curves for dust. Tracking them down and deleting them can be a pain. The ability to select all curves below an adjustable length could be really useful to keeping the file clean.
Thanks. The Split engine shouldn’t create a tiny pieces of curves, that said, I agree with you that controlling this configuration ON/OFF would give more freedom to users to decide when they would like this behavior to work or not.
