New Thought has a visual problem in that the bullet and placeholder briefly overlap the next thought until it shifts down.

It has a perceptual problem in that the animation duration is the same duration as larger changes, such as collapse context or toggle table view. For the right "feel", the animation duration should be proportional to the "mass" of the changes, i.e. a T-Rex moves slower than a chicken.

Steps to Reproduce

- a
- c

1. Set the cursor on a
2. Activate the New Thought command

Current Behavior

When a new thought is created, the bullet and placeholder briefly overlap the next thought until it shifts down.

Note: The placeholder ("Add a thought") is only shown in training mode, so is not captured in the video.

Expected Behavior

1. Speed up the tree-node's transition (normally layoutNodeAnimationDuration) by 50% on New (Sub)Thought only.
2. Fade in the bullet and placeholder of the new thought with fastDuration or veryFastDuration and ease-in-out so the overlap is less noticeable.
