Currently, the web app allows library sorting only by "title" and "author." It would be great if you could allow additional sorting methods, particularly "most recently accessed" - this would aid situations where the user is moving quickly between different platforms, allowing them to quickly view and open the resources they were using on those other platforms. Library sorting of this type should really be made universally accessible across the platforms, especially since Logos does not allow layout syncing across platforms (for good reason since the platforms are not feature-agnostic). It would also be nice to have access to tags within the library on the web app.
