This is a minor feature request. "Quick add" on macOS supports arXiv by using the arxiv: prefix that precedes the IDs — could iOS bookends support arXiv in the same way? This is minor because I know I can search arXiv in iOS online search, but autofill is quicker
Also, do you think it may make sense to rename "Autofill from internet" to "Quick Add" so it is more consistent with the desktop version?
