<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I'm not 100% sure this will still work as now the rotation property isn't being updated.
>From the docs:
"The value of the QML property will be updated after the animation has finished. The property is not updated while the animation is running."
We're doing this when the animation changes, which is a documentation grey area. I think it will be OK, but I'd like you to check before shipping.
Start the animation then pause + start and check it resumes from the same place.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Finished probably also meaning whenever it stops.
Nonetheless I played around with the running property and the rotation continues exactly where it stopped.</pre>

This helped reducing the massive plasmashell CPU usage during file copying (ie. notifications spinning). The results varied greatly but it can't hurt to use the Animator nonetheless since it doesn't propagate the new rotation angle constantly.
