Lovely update!! Only thing I’m missing is showing the File name in the lightbox so I know which file I’m looking at.
Also out of curiosity, was it considered to use the two-panel navigation to open files instead of a lightbox? This would allow to maintain context, make edits to entity, write notes, as you have the file open. This might not be relevant when the new Files Unit in entity view is released for a to-one file. then the entity itself acts like the file, so to speak.
Follow up:
Will it be possible to drag and drop files directly into a gallery view to make new entities/attach files to entities?
