What is TinyMCE Advanced?
Taken from the developer’s webisite.
“This plugin adds 16 plugins to TinyMCE, WordPress’ wysiwyg editor: Advanced hr, Advanced Image, Advanced Link, Context Menu, Emotions (Smilies), Full Screen, IESpell, Layer, Media, Nonbreaking, Print, Search and Replace, Style, Table, Visual Characters and XHTML Extras. Together these plugins can add over 40 new buttons to the toolbar, which is now two rows plus one hidden row.”
TinyMCE gives you the ability to arrange the buttons and drop-down lists in by going to Dashboard > Settings > TinyMCE Advanced. Here you can choose an appropriate layout for the functions you will use.
IMPORTANT: Arrange the icons so that the posting form doesn’t expand too far to the right, because the right sidebar will overlap the post box.
