Each collection has a horizontal scrollbar which is very helpful. For any reason the File storage view has no scrollbar. On adding some new columns (programmatically) I thought first they were not added but they were there, just not being able to scroll to them (hidden on the right side). To see all columns you need to make the visible ones smaller manually. A horizontal scrollbar would therefore also be helpful (with regard to same behaviour as in collection view).
Thanks for bringing this issue to my attention. I have escalated this to engineering and will keep you updated on the progress.
