I have been thinking, would it in some usage cases be good to have the option to arrange the files in groups (albums)? For example…
Album A
File 1
File 2
File 3
Album 2
FIle 1
File 2
and so on. The Album could be collapsable so that one doesn’t have to see all the individual files at once, but instead he/she would see the album names / covers / description. After opening the album the individual files would be shown.
