It would be nice to have a few more options here! Perhaps “to work on.” But ideally, it would be nice to be able to add one’s own categories, and to organize the folder by them.
Did you find the lists feature for categorising items to be helpful for this? Or do you mean something to group together smaller units (images, transcripts, notes, sections). In which case, a “tagging” feature is something that we plan to introduce soon!
