I really like the automatic title case option provided by JabRef. I use it automatically when cleaning up new imported entries etc. Unfortunately, many journals I publish in request the capitalize rule according to the Gregg Reference Manual, see, eg.,
Would it be possible to include a tile case based on the Gregg rule? Maybe one could include an option which rule to use when title case is wanted? Gregg rule should be simple to implement, "Traditional Chicago" seems to be more complex (see link above).
Thanks for considering this feature request.
