WordPress posts already have a preview feature but many a time you have to open you WordPress site for previewingthe changes you have made. Suppose you have installed a new plugin and you want to know how its new features are looking in the front-end of your WordPress blog or when you activate a new theme or change your reading or discussion settings etc. You have to go through one or two click for previewing your website. Sometimes you like to open yourwebsite in new tab so that you can carry on with your changes in dashboard and refresh your webpage everytime after making new changes. This thing is a little bit time consuming and its not handy.
