Hi
I'm afraid I have nothing further to add. As Balok and Andrei have pointed out this would require javascripting, and may end up a mess.

Creating two columns also requires a javascript, which has to loop through the entries and start a new column when it hits the 5th of 10 entries (if thats the number of entries you hav set OCD to display)

It can be done. I've done something similar previously. Look in the forum for postings on 'LP mode'. That should give you an idea of what you need to do.
