You know what would be nice... a keyboard shortcut that could apply ease out/in to a pair of nodes in Effect Controls automatically, including by KB shortcut.
Operatiion
1. Create a pair of keyframes that move the image, say for Scale and Position. One for start and one for stop on the Position and Scale Effect Control timeline.
2. Select all 4 nodes
3. Right click and choose "Auto Ease" (new function) or tap a keyboard shortcut
4. It applies ease out to the first node, and ease in on the 2nd node.
OR if there are only two sets of nodes and they're aliglned, Auto Ease would apply without having to select them.
Or how about this idea: Putting a checkbox option in the Effect Controls panel so it would apply Auto Ease whenever it saw a pair of nodes that started and stopped a move. Get your AI engine cranked up. That should be easy.
