In SharePoint 2013 site. the quick launch navigation shows 5 items by default in the recent items. And we need to increase that number to 8 or 10. I don't find any out of the box ways to do that and even google is not helping. Could you please suggest How we could achieve this.Is there any third party tool or any custom scripts We may use to do it.Thanks in advance.

Go to Site settings
Then go to Navigation settings
Structural Navigation: Editing and Sorting
Then go to Current Navigation
Add heading , it will give you browse option.
Browse your list/library/page and select , and add a title.
Your browsed item will be available at left navigation.
