GP3: filtering the list of modifiers used

it's a nightmare when we use too many modifiers and we want search on a modifier that used on a specific layer/material/Vertex group (or by pass index).

my idea is to have an option as checkbox to filter them by the active(selected) layer or material or vertex group, eg: whenever we change the active layer the list get updated and kick out (from the visible list of modifiers ) the modifiers that don't influence the active layer ..... this helps to quickly manage the desired modifiers that related to selected layer so speed the the workflow for artist
