We need some enhancement on the removing collaborator for certain sub folder. For example I grant Amy to the parent folder which consists of sub folder A, B & C. However, I want Amy to only view sub folder A & C. Thus, I need to remove her name from sub folder B but BOX doesn't allow me to do so. My suggestion to at least add a function in order for the owner of the folder to remove collaborators for certain sub folder. Thank you.
