DOTween

DOTween slides a menu selection smoothly instead of snapping between items. In Mark Brown's Unity recreation of the Echoes of Wisdom echo row, a DOTween slide of about 0.1 seconds replaced the one-frame jump between items. He compares the result to butter in a pan.

Snapping from one item to the next in a single frame looks ugly, and a tiny animation makes the menu feel responsive and polished. Quote: "Now it slides from one echo to the next, like butter in a pan."

DOTween made a hold-to-accelerate list scroll easy to build. The acceleration option divides the slide animation's duration by a value that builds while the stick is held, so a 0.1 second move gets faster and faster the longer the player holds a direction.

Very fast scrolling makes you lose your place, so it is paired with a bar showing position in the full list. It is a cheap quality-of-life fix that keeps the original layout. Quote: "you suddenly have a bar that moves faster the longer you hold the analogue stick down."
