P: Ability to identify pictures not assigned to an album

Yep. Need this badly, hoping this feature would arrive in CC much sooner.

Please add 'Not included in any albums' filter in Refine search in Lr Classic.

Whenever I delete an album, Lr CC tells me that the files in the album will not be deleted and will be kept in the All Photos. This is very unhelpful as, with time, lots of files which I no longer need build up in Lr CC creating junk and eating up space on mobile devices.

It would be great to be able to go and filter out all files that are not included into any albums and delete them from All Photos.

We really need a feature to filter and find photos that are not assigned to any album. I just converted a 100,000+ photo library from Apple Photos to Lightroom CC. I then reorganized many of the folders (partly because I had deeply nested folders with long folder names that won't fit on the desktop column display on the left in Lightroom CC - that's actually the first problem, and a silly one at that). Anyway, during various moves and imports, I inevitably ran into problems where photos got orphaned, as they did not belong to any album. Right now, it's impossible to find them in a large library, and fixing this manually is a nightmare. Apple Photos supports creating smart folders that can filter by photos that are not in any album. This is a badly needed feature for Lightroom CC, too. 

There should be a method of filtering out all the photos that are taken / uploaded that are not in an album or collection. Currently there are no way of doing that. For the mobile version, it used to be that you are able to navigate to an album, and take a picture while in the album and the picture taken will be automatically added to the album. But that seem to have changed. I would like to have all my photos organized, and be able to know which photos are not organized.

It's great that we can now see which albums a photo is in but it would be better still to be able to see all photos which are not in any album.

Please can you comment on what the recommended work flow is for sorting photos into folders. Because without this feature I can't see how you can do this reliably without a way to check.

If you can't actually sort into folders reliably then the folders feature is not usable in a professional context. And without folders I don't see how anyone could use the software professionally.

So like many above I'm totally baffled how anyone is using it, except with clunky work around. I'm using it for a relatively small number of mobile + drone photos at the moment as a trial. But all SLR pictures are going into classic due to this missing feature.

I also really need a means of identifying photos not in albums.
It's extraordinary that this is not yet possible.

Great feature that helps organizing your library much easier. Shouldn't be hard to implement.

In Lightroom CC, photos are organized by date by default. You can then put photos into albums (similar to collections in Lightroom Classic). You can see what albums an individual photo is in now. But if there is a photo in no albums, there’s no way to find it.
