Lots of potentail but not ready for primetime
Much nicer interface than that of Zotero App for Mac but it still lacks some basic features (e.g., moving/copying a paper into a group collection) and has annoying bugs (e.g., not showing any papers in a new collection created in Zotero for no apparent reason). There’s also no user manual and the online “help” is very limited. $14.99 price tag is hefty for what you get. Worth revisiting when it’s more fully developed.
