action/filter suggestion

Hello.
I wonder why this wonderful plugin is not having hook system yet?
i would like to be able inject validations/modifications into fields before output/after submit etc. i’ve made a custom hack for this, by adding my own

do_action('modify_redux',$meta_field);

somewhere inside rpr_register_form() in line 192 or so, but it will be lost if plugin will be updated.
