I have 2 suggestions:
1 I would like to be able to link records within an EN library to one another. For instance, one record may be a review of another, or cite another, or be closely related, etc. What I have been doing is putting in tags with the record number I want the current record to be linked to prefixed by # in the Notes field. So at the moment this is simply a mental note, and I still have to manually navigate to the indicated record. What would be nice is for the #RecNo tag (or similar mechanism)
to form a link that would directly take me to the indicated record.
2 It would be nice for there to be a display field in the main (reference) pane to would indicate what group(s) the currently selected record belongs to.
