Letting the User Change the Sidebar Width in CWiki

Recently, I’ve been working on what I thought was a simple feature – changing the width of the sidebar in the CWiki wiki program. There were two ways the user could do it. First, they could set it manually in the “Preferences” page. Second, and more naturally in my opinion, they could use the mouse to drag the separator between the sidebar and the main article area to the location they wanted it.
