The Issue

Basically that after upgrading Joomla, my TinyMCE WYSIWYG (What-you-see-is-what-you-get) editor halved its number of buttons and I couldn't add code snippets... 

The Fix

Just installed JoomlaFCK WYSIWYG Editor, an editor I use with my day job's MediaWiki software and it's pretty amazing.  Incredibly cross-browser compatible with some MS Office 2007 styling and fortunately maintains it's previous button layout.  The features such as full-screen editing, emoticons, and pasting from MS Word documents make it the best in the market IMO.
