Is there any way for Members to manually delete old Notifications? 

I can only find where the Admin can set an auto deletion for Notifications from 1 month plus in AdminCP. Seems strange that there is no delete selection to right of the list of Notifications. Even at one month if a Member has a lot of Notification choices selected they can really pile up.

Theres a plugin in Marketplace to clear notifications. 

OK thanks. There certainly should be an item to item deletion function or a clear function built in...IMO. I'm trying to keep things "native" but will look into that Plug-In.
