Add Easing to animations

[qhouz]

Is your feature request related to a problem? Please describe. The animation looks very raw, the animation is linear, it causes wild discomfort when using it.

Describe the solution you'd like Add some Easing, it's easy enough to implement.

Describe alternatives you've considered I tried to change the animation speed, but now it's really fast.

Additional context Add "Easing type" in "Effects" tab, to customize it. You can make easing “Linear” by default, but I consider to make it look like it does in Windows (I guess it's ease-out, not sure about it)
