Nice try, but still missing (and broken) key features – Mendeley (PDF Reader) Review

I love having my digital library at my fingertips, and with exporting to iAnnotate, it works out alright, I suppose. However, the search feature is broken. "No matches" for title, tags, or author, which is frustrating. Also, I'd like to echo the need for multiple tabs in the app. Designers - are you out there? Is there an update coming?? Please?
