## Panel updaters (apply the registered filters/remove the unregistered filters)
Registered/Unregistered filters only apply to the panels/inventories/scenes/fragments/controls/userdata as you refresh/update them via their methods.<br>
LibFilters provides updater methods to do that for you, which you can manually call as you need them (e.g. via libFilters:RequestUpdate(LF*_filterTypeConstant).<br>
