My idea is quite simple. It would be really helpful to be able to select and delete multiple slides. Think Powerpoint slide review (see attached) which gives you a thumbnail view of an entire project.
Benefits:
-users would be able to delete more than one slide at a time
-users could move a whole section at a time
-users would get an overview of their course
I working with 100+ slides, trying to delete without this feature is not fun. Please upvote!
