Clean Up Your WordPress Dashboard by Adjusting Screen Options
You’re in your WordPress dashboard all the time. Why not remove some of the feeds that you never read?
In case you may have missed it, there is a “Screen Options” tab in there that you can pull down for adjusting your Dashboard’s appearance. Uncheck the items you wish to hide. You can also change the screen layout and select to display the dashboard widgets in 1-4 columns. Play around with it and customize your dashboard to suit your needs.
