Yes, that's exactly what I was asking for.
At the moment I'm doing it via ag:SetEndDelay() and then pausing the animation at onFinish (which is fired if the animation itself is done and before the delay starts).
But I wouldn't consider this as a good practice. It's rather a bad hack than 'using a feature'.
I introduces some unwanted problems too.
It's even worse with rotating than with fading or translating. Afaik the animation is the only way to rotate a frame (let's say an action button that represents a
clickable area). The only other way to rotate something is SetTexCoord(), which applies to textures only.
