 <title>Things that <app>Meld</app> doesn't do</title>
 
 <p>
+Have you ever spent half an hour poking around an application trying to
+find out how to do something, thinking that <em>surely</em> there must be
+an option for this?
+</p>
+
+<p>
+This section lists a few of the common things that <app>Meld</app>
+<em>doesn't</em> do, either as a deliberate choice, or because we just
+haven't had time.
+</p>
+
+<section id="missing-change-fixed-alignment">
+<title>Aligning changes by adding lines</title>
+<p>
 When <app>Meld</app> shows differences between files, it shows both files
 as they would appear in a normal text editor. It does <em>not</em> insert
 additional lines so that the left and right sides of a particular change
 are the same size. There is no option to do this.
