It would be nice if you could set preferences to select which fields are displayed in different databases/groups. eg. I have a group of academic papers and a group of component datasheets. I would like to change the settings so that when I select the 'datasheet' group the user defined fields of 'component number' and 'company' are displayed instead of 'author' and 'volume'.
