Default Checked Link Wordpress Plugin - Rating, Reviews, Demo & Download
Plugin Description
The default link functionality is to open on the same browser page. If you want the link to be opened in a new page, you need to create the link and then enable the check box. This can be quite annoying when you always want the link to open in a new window.
This plugin enables the check box to be ticked by default so that a link always opens in a new window every time you insert/edit link.
