I want to delete Notifications

I either read, delete or keep Notifications. Now I can only read them and it doesn’t indicate I’ve read them. I have to scroll thru the whole list of notifications to find the one I want to keep because I can’t get rid of the ones I am not interested in or ones I’ve read. You should fire the people responsible for this last upgrade and go back to the previous version that worked better. Unless SA doesn’t care about their readership, then keep it as is.
