Add option to remove (instead of hide) unnecessary filters

chrisolof → changed the visibility of the branch 3509467-add-option-to to hidden.

Hi Chris, I really appreciate the changes you've made to the module.
I would also prefer to remove unused form fields from the html code instead of just hiding them in cascading styles.
But I've found an issue: if I split a form into two blocks and set it to remove unused fields instead of just to visually hiding them, then changing the state of one form (e.g. ticking the checkbox) will clear the previous state of the second form (e.g. filled input).

Not sure how feasible it is to merge multiple form states behind the scenes.

I would put that down as a bit of a blocker to have the module fully support this feature, although the patch as it stands is very useful for some particular use cases.
