P: Ability to identify pictures not assigned to an album

Maybe I'm missing something. 
I thought that the previous Lightroom allowed you to view photos that were not in an album.  If this is really a missing feature then what is Adobe's thought process for organizing photos on a computer?

I like to see which picture are not in an album, but in the still in the all folder so I clean up space

I would also add that I'd love to be able to identify photos not in a specific set of albums. In Classic, I organized all my photos into some general categories (hiking, road trips, travel, events, etc.) and then by the specific event/location/etc. That allowed me to easily find photos and know where all my photos of things are. Organizing them by date has no real relevance to me.

(Though as a sidebar, that is how my archives are organized, but that way I can find a specific photo in my keepers, find the date in the metadata, and then find other pictures from that same trip/event/etc. in my archives if needed.)

But in Lightroom CC, since my folder organization has been combined with my collections, I now have albums which help my find those events/trips/etc.  and I have albums for "best of..." or other specific things. What I'd like to be able to do is find any photos that are not in my main organization folders. (I have three: Personal, Work and School, and Other's Photography. I could combine them all into a single folder, but only if I could better control the sidebar width so that I can still actually see my more deeply nested folders.)

With the August 2018 release of Lr CC 1.5, Album membership information has now been implemented.

I have 25,000 photos in all photos but only 20,000 that are in albums.  I need to identify these so I can put them in albums or delete them.  

+1 for request to find orphaned photos, matching metadata but not in a selected folder.
ie. Photo taken in 2017 but not contained in my Album named 2017

Put that in as a separate request Selondon. I'd vote on it!

Plus LrCC Team, please include a way to identify what Album(s) a Photo is in. This could sit in the info field.
