If "Animate" is enabled, the XCenter frame will be animated
when the XCenter is opened or closed.
This does several things:
- It enables
the system animation for the XCenter (which is only displayed if you
also enabled "Animation" on the first "Window" page in the
"Workplace Shell"
settings notebook).
- It also displays an extra animation to unfold the XCenter bar.
- If "Auto-hide" is also enabled,
the XCenter is more slowly hidden.
