It would be nice if it was possible to filter items by date added / published etc. If we could specify the year range or date specifically it would nicer. This will allow us to find publications done in the last few years for a particular topic especially when we have a large library. Another use case is when you are adding several items together in a single day and after some day want to filter out those papers together. Using labels works but creating custom labels for each date is not an intuitive solution.
