Hmm, I’m not sure I understand exactly. By default it uses each subfolder as an album / collection that you can pick on the home page. You can also configure custom collections/albums consisting of arbitrary directories. You could also configure e.g. an “all” collection with all the photos combined by listing the root directory(s). Is that what you meant?

Thanks! Do you mean explorer-like folder browsing?

It’s quite impressive how much the Immich folks have achieved in a relatively short period of time! I’m glad you found something that works for you :)
