There are not much curves in Nomad so far, and those are older than pathes.
But it would be consistent if they would react almost same.
Drag one point over another for deleting, tapping on curve for smooth or sharp corner.
Another feature which comes in handy is to move two points at once.
Example:
If I move the lower point to the right till same position of top point, the top point moves with it to the right.
Actual behaviour is stopping, which is stopping creative process in finding right setting as well.
Just a tiny one.
