Hi there,
in the Keyframe Velocity window there is the "Continuous (Lock Outgoing to Incomimg)" checkbox, which when clicked, copies the incoming speed of a keyframe to the outgoing speed, and locks them together.
Every time i need to ease into a continuous motion, I find myself manually copying the outgoing speed to the ingoing before locking them. This can happen multiple times per work session.
It would save me a lot of time to have a choice of locking direction - Incoming to Outgoing or vice versa.
Thanks for reading!
