Photo organization into Albums in apple photos

I can create photo Albums and put photos into the Albums ok. but I have many photos that have not been put into albums yet. And always have new ones. When I go back to the "Photos" view, to see all the pictures, I cannot tell which ones are in Albums , and which one are not? how can I tell, so I can continue organizing them?

I use iCloud photos, so the links between my Mac and iPhone work fine.

Thanks..
