When entering tags after you have your complete collection entered, it will be a hell of a job, since you need to work your way through your collection one DVD(boxset) at a time. I was thinking that it should be easier to do, if only we would have the possibility to filter (how is not important) and apply the desired tags and/ or changes to all DVD(boxset)s in the current filter-output.

For example:
I mark every animation movie, then I would like to apply the filter that filters on the marked DVD(boxset)s and finally I would want the tag "Animation" to be applied to every DVD(boxset) in the filter. That means that is should be possible to enable the tag "Animation" on multiple DVD(boxset)s at once.

Hopefully you understand what I am trying to say.
