SharePoint 2010 Web Part Pages to display Quick Launch Section and Custom Logo

SharePoint 2010 Web Part pages do not display quick launch section and custom logo. This could be easily fixed by making changes in Master Page (v4.master). Make sure you always work in the copy of the master page and have original master page for backup.

To make Quick Launch appear in Web Part page, find the following two sections and comment them.

To make custom logo appear in the Web Part page, find the tag whose name property is "onetidHeadbnnr0" and change it to something else, like "onetidHeadbnnr1" in the master page.
