I'll be working on a class catalog (after not doing it a couple of years) – I just recall that copy fitting was a bit of a pain, making sure the bottoms of all the columns (3) lined up, by tweaking the leading, space before/after the headings etc., etc.
Just wondering if getting a plug-in like typefitter would be worth it:

Anyone try something like this? Other tips/advice appreciated.
