I'm still leaving the pipe symbol | as the separator for multiple values for a particular column. If people would prefer a different character, I'm open to changing it, but I think that character works fairly well in practice.  The column delimiter is now automatically calculated in v1.3.2.

I actually prefer the semicolon for multiple items. It's practically obsolete in current writing use so there should be no clashes. It isn't a special character and you can reach it more easily to type on keyboards (for those like me who will do a lot of csv editing at a PC, on German keyboards it's on the same key as a comma).

And not very importantly but still it's consistent with other applications using semicolons for multiple entries fields (Calibre and Mediamonkey come to my mind).

So one vote for semicolon from me. Maybe some more weigh in, too.
