Can understand the reasoning for a one location approach but I would prefer if each app such as gallery, forum/attachments, cms etc still keeps its own individual folders, even it's under a single uploads such as /uploads/gallery/
the main reason being for own use is backup reasons, but also maintenance and trouble shooting as I have large numbers of files in each folder app
which if there was all-in folder, where all files from all apps went in say a '/uploads/monthly_2024_11/' feel it could be very unwieldy imo
