Is there a way to organize pictures in PB into folders that suit my preferences. When I transfer pics they seem to display as the bottom level folders only. i.e I transfer folder 1 which contains 3 sub-levels of folders but what displays in PB is all the 4th level folders. This can be very unwieldy. Same with bookmarks, can they be put into folders as they are in other browsers?

Unfortunately no, no folders yet for bookmarks , photos, videos nothing of the sort if you put folders of photos on the playbook for instance when yougo to view them you will see the playbook disregards them. This is a feature they are looking to add but as to when and if they will who knows.
