Spinner overwritten

Hi,

I have replaced the spinner in /usr/share/enigma2/skin_default/spinner with something better fitting my taste.

Unfortunately this doesn't seem to be a good idea, as during each system update the first 4 wait?.png file are usually overwritten (although I never recognized that that had actually changed).

Is there an official way to use customized spinners (e.g. similar to the bootlogo using /etc/enigma2 instead of the original location)?

If not, would this be feasible?

Kind regards

Hounce
