A question on a recent training course reminded me of InDesign’s Balance Columns feature which is easily overlooked.
If you’re the kind of person who can’t stand unbalanced text you’ll recall it used to take a fair bit of manual adjustment to make columns line up evenly.
In CS 5, the Balance Columns checkbox was added to the Text Frame Options dialogue box.
The feature works only on multi-column text frames. Select the frame and got to Object> Text Frame Options (ctrl/cmd+B).
