ACE is the editor for Joomla, which can be used as an HTML editor and just as he is. Will be very useful for programmers, designers and SEO optimizers.
In addition to its primary purpose, this plugin allows you to see the HTML markup that improves the overall visibility of the text, and helps you quickly find necessary item.
Unfortunately, it is not as stable as I would like to replace some characters to joomla 2.5 (at least for me).
The ability to quickly access the required tags.
Easy to use and great code highlighting.
Simple integration into the available settings and parameters.
