Timing before more keyframes

When a scene feels flat, adding more movement is not always the next step. First check when each action begins, how long it lasts and whether the viewer has time to read the result. Timing changes can make the same set of layers feel much more deliberate.
Separate the main action from the response
A button press and the panel it opens belong to the same event, but they do not need to happen at the same instant. Make the cause legible, then let the response follow. Review the animation without stopping playback so you judge the sequence as a viewer will experience it.
Refine one variable at a time
Change duration first, then spacing between layers, then easing. If you change all three at once, it becomes harder to understand what improved the result. MotionUI brings sequencing and a visual easing editor into the same workflow, so you can make a focused adjustment and preview again.
