I was using a trial period of Lightroom desktop and it looks like there are more filter/search options than in the mobile version. I'd like to keep my photos in albums and the desktop version lets me filter by whether photos are in an album or not. I can't seem to find this option in the mobile version on my iPad.
Is it possible to do this somewhere in the mobile version or will it (hopefully) be added later on?
In the meantime, if you still have access to the Lightroom Desktop app there's acrude workaround you could use: run the search on LrDesktop to find all images not in any album, then create a temporary album into which you add all those "not in any album" images. That temp album will sync to LrMobile where you could work you way through it to place all contents into "proper" albums (use the "Move to" option so that as they are added to the target album, they are removed from the temporary album). Not ideal, but certainly "doable"
