WordPress is a powerful Content Management Software (CMS) but it lacks basic good editor. You can not use different Formats, adding table, justify alignment etc. One needs these basic editor functions to write a beautiful post just like in MS-Word.
To overcome this problem, today, we’ll install TinyMCE Advanced WordPress Plugin, which adds number of features on our WordPress visual editor.
Firstly, goto Dashboard -> Plugins -> Add new and search for TinyMCE Advanced plugin and install it.
You can also install it from https://wordpress.org/plugins/tinymce-advanced/
Activate the plugin after installing it.
Now, goto Settings -> TinyMCE Advanced
You’ll get screen like this.
Here, you just need to drag buttons from Unused Buttons to upper rows as shown in above image.
This plugin will let you add, remove and arrange the buttons that are shown on the Visual Editor toolbar. You can configure up to four rows of buttons including Font Sizes, Font Family, text and background colors, tables, etc. It will also let you enable the editor menu.
Finally, click on Save Changes button.
Now, open a new post or try to edit existing WordPress post.
You’ll see new TinyMCE Advanced Editor instead of default WordPress Editor.
