It has happened quite often, that a client says to me: I can’t find a way to edit this. I don’t see that option on my screen.
Well, it may just be that you have not discovered the Screen Options on the WordPress dashboard. When you are logged into your dashboard, in the right upper corner of your screen there is a little tab marked “Screen options”. Click it and it drops down a panel with multiple checkboxes, that let you turn on and off a number of control panels that you might not use and wish to hide.
For example, you might not use custom fields, or comments and wish to have more space on your monitor to see other relevant items when you work on your site. Simply uncheck the boxes and immediately you will see the updated look of your dashboard. Another brilliant idea by WordPress!
