Thank you for your extensive answer, it feels nice being heard.
In my opinion it makes sense to first discuss the big picture. Only when this is clear and agreed upon it makes sense to really brake it down to manageable tasks, ergo issues on Github. Otherwise you risk implementing stuff, that soon becomes obsolete when the concept evolves. But alright, I will feed some of my ideas to Github.
Because of that, I thought it to be sensible first to have a visualization of a rough possible concept, even when everything is just copied together. I didnāt know yet if anybody would anser my thread 
If the only thing about my screenshot bothering you is that it is only done roughly, well great, tell me in what form you need it and I try to deliver a UI that meets the quality expectations (no dev skills though).
Agreed, but my first screenshot shows a files view just in order to create albums from folder(s). If for instance in the context menu in files there is an entry ācreate album from folder contentā which then appears in Photos, this would maybe a nice way of having it both ways. And a list view for managing an album would make this easier, see more on albums below.
Well, here I donāt agree in terms of deleting. When previewing photos, in my opinion you also need to have to possibility to remove them. Otherwise it is just a cumbersome workflow to change between Photos and Files.
I understand that this is difficult and no matter what, some will complain. Like me right now 
Let me say this:
- I think (hope) my screenshots above highlighted the advantages of virtual albums that are seperated from the filestructes folders
- It would help creating a timeline for low performance servers. Right now, I have a timeline containing 42ā688 pics where it is impossible to go far back (even on mid-range performance: Xeon D-1518 and 64GB DDR4). And I have an āalbumsā view, where I first need to click through to my Photos folder where everything is organized in yearly folders with kind of album-like folders below. But some are also just miscellaneous pictures not worth of an album
- I was also giving some thought, if I would really want to make the effort to recreate albums from folders. The answer is yes, if I could select multiple folders and with context menu ācreate separate albums from foldersā where everything within the folder is displayed flattened in the album. But surely this is very individual. But I doubt that you guys know perfectly what everybody wants. Maybe we could do a poll? How do people organize their pictures today and how do they want to see them within photos?
Last question: what solution do you see for keeping common albums between users? I run Nextcloud in a jail on FreeNAS, therefore all data is mounted to the jail and exposed as external data. Seems like the majority of (9, lol) users do something like this according to this poll. When sharing a folder (i.e. album) this appears in the shared folder with the other user and cannot be moved to his photos folder in the external dataset. How could this be solved?
