I use split-and-span columns frequently in my work. Often, with lists of names, I'll have that one name in a column that is just too long and wants to wrap. If I could adjust the column width after using the split-columns, that would be very helpful. As it is, I either have to decrease the type size or increase the right side margin, which messes with the body text width. I don't want to create a separate text frame as this is too common an occurrence in my work, and I'd have to be dragging and anchoring all over the place. This request may be impractical in terms of backroom coding of InDesign, but if it isn't, maybe someone can try?
