I really enjoy using Bibdesk. One thing that would it considerably better (from my standpoint) is some additional intelligence on the autocomplete feature on the Author field. I constantly encounter an author name (for example, "G. Hirzinger") of a paper where I can't recall the first name. However, I like to store the first name ("Gerd Hirzinger") in my bibliography file. Bibdesk won't autocomplete in this case, but it would be nice if I either put in the last name ("Hirzinger") or if I typed "G. Hirzinger" it would automatically insert the first name.
