[Feature] Tree structured album folders

The feature

When someone has a high number of albums the browsing is clumsy and slow.
As I heard from my friends and photographers, everyone is looking for a photo storage service that could provide tree stuctured albums.
I would suggest to introduce a new functionality to structure albums in folders. Albums then would act like files.
There would be a new action button "Create folder" that creates a new folder. Folder context menu has items "Delete folder" (deletes only empty folder) and "Move to" (moves folder to any other folder). Folders would be shown (ordered by name) before albums in the current tree node. Album context menu has a new item "Move to" (moves album to any another folder).
It wouldn't change anything for those who do not want to use folders, but it would be a huge improvement for the majority of others.
