1- Folders can be created, renamed, moved, copied, and deleted right on the PB360.
2- Files can also be copied, moved, renamed or deleted locally.
3- In addition, you can choose how to display book files (by filename or by book title, if available in metadata) and how to sort them.
4- The bookshelf transparently aggregates folders from onboard memory and any installed flash card into a unified folder list.
5- It tracks books with icons by location (onboard or flash card), whether they've been opened, and whether they've been finished.
6- It is possible to flag specific books into a separate favorites list.
7- The default GUI home menu displays the last two opened books.
8- The power button can be configured to display the last ten opened books; this list can be used to switch from one book to another without having to quit to the bookshelf.
9- The GUI home page can be re-skinned to display as many as 10 recently opened books.
10- I'm sure I'm missing a few file management features, too.
