I've just downloaded it and I'm loving the feature set this has. Being able to do variable heartline and friction is an absolute godsend for some of the weird stuff I like working on.
I've noticed what I think is a bug when using curves and geometric sections together. When you place a geometric section after a curve the pitch and yaw carry over from the roll, even when using lead out. So for instance trying to create a lift hill with a upward curve followed by a straight geometric section results in a curve followed by an incredibly tight geometric spiral ( more than 50 rad/s usually ).
If there's anything I'm doing wrong with how I'm configuring my nodes, I wouldn't be surprised, so it might just be on my end. I'm running the mac version on an M1 too, so it could be Apple being Apple
