Photo folders and ordering

I realise that this is a topic that has been discussed, but please bear with me.

i) it seems that plex only allows one level of folder nesting. So I have photo’s ->Walks->walk. I only get all the walk photo’s together. This has meant that I have to create a folder for each, which appears in the photo’s folder. I try to keep the screen as uncluttered as possible so this is a pain.
ii) It seems to display photo’s in reverse chonological order, so when viewing I have to scroll to the end to see my photo’s. When playing it then plays in reverse chronological order, starting at the end of a holiday and working forward. There seems to be no way of sorting or filtering.
iii) Please do not say use the timeline. A more pointless tool it is hard to imagine. Assume 7 people are taking photo’s on the same day of different things, with each camera giving different naming conventions, timeline creates a mess that makes it unusable. Renaming each photo is clearly not practical.
iv) I have also found a case in which it has put photo’s from different folders on the server in the same folder on Plex despite a 1:1 link between folders at both ends…

In short, as many have said, this part of plex is not really much good.
I may have missed some basic functions, at which point, sorry Plex. But, I’d be very grateful for any advice.

P.S. To add insult to injury, having put in all the additional folders it has failed to save them. Incidentally, one has to click all the way to the directory for each folder, so if you have ten subfolders and four clicks to get to the correct folder, this combined with the internal clicks to the process can mean about 8 clicks minimum to create each photo ‘album’…no comment necessary.

OK, try this, I have all my photos on drive M which is a partition of a local HDD in my pc.
It has a large collection of folders with in folders all over the place.
I tried to create a library to the top level Local_Photos folder and it failed.
But if I link Plex to the Windows Library called Photos ( which is pointing to the very same folder ) Plex is happy to read the ‘library’. No error.
