Zotero is exactly what every researcher needs, and few (if any) do it better than Zotero. However, on iPadOS, until a few basic tweaks are made, Zotero will not be better than a well-organized iPad files app. - Annotating with an Apple Pencil comes in a few colors, all of which are completely opaque. There is no sense in highlighting anything if you cannot see what has been highlighted. - While editing file information, leaving the app (not closing, leaving) erases all progress made. This is particularly frustrating when trying to fill in information needed for a citation. Forgot what year the article was published, so you went back to the database on safari to check? Too bad, when you come back the title, author, publisher, and everything else has been lost and needs to be entered again. - After a file has been made, you cannot add attachments. This would be useful for articles that come in two PDFs, text and examples.EDIT: The developers respond to comments and seem to genuinely want to improve the app. And with the number of bugs fixed recently, that is apparent. As bugs continued to be ironed out, this app will be indispensable.
