Animation curves look unnatural
Most, if not all, GNOME animations use curves that tend to accelerate excessively, leaving a high velocity especially in the last frames, leaving a somewhat too linear (or unnatural) impression.
It would be nice to do a brief analysis of the existing animations, e.g. Clutter.AnimationMode
s and durations, in the aim of modernizing those and making them look overall less heavy or confusing.
For example, right now most animations use the Bezier cubic "ease-out", which may not be the smoothest-looking.
A nice demonstration of the CSS easing modes exists at this URL: https://matthewlein.com/tools/ceaser
