I have been trying to learn how to use the parent child tags.
I thought the this only affected the align functions but I can see that also other things like alpha and effect tags are changed when applying a parent tag.
As far as I can see the only thing that is not applied by default is scale and for that you can use the scalechildren="true" to change.
But what if you want to have an alpha setting only on the parent plugin ?
I have not found a way to exclude that for the children the same way as with scale. Setting alpha="1" on the children does not override the setting on the parent.
