A minor thing, when entering keywords in the recommended format (one per line), you only see one full keyword on reference list view, with just the top few pixels of the second keyword/line being visible - looks a bit ugly.
a) Is there any reason why keywords should be entered on multiple lines, and
b) can display of multiline entries in notes/keywords fields in reference list view be tidied up easily?
The problem doesn't occur in Lucida Grande font, but I then found that I had a carriage return in the title, the removal of which sorted out the title field in both fonts.
So, in Lucida Grande, multiline fields don't cause a problem in column view, but Helvetica leads to untidy wrapping.
