Exclude photo albums in Apple Photos

I should be able to hide photos in certain albums from my main library

or the "hidden album" stuff should be "hidden albums" and it should allow multiple named albums

one of my silly little Software ideas

I currently have Smart Albums which exclude certain albums so I can use those as a pipeline (i.e. if I'm looking for good Screensavers, I'll have a "Not Screensavers" Smart Album so I can browse all excluded images, to add more to my Screensavers album)
