Because there is currently no integration of ACE into Joomla I decided to start building one. And here is the first version of it.
This is the very first version which just provides the ACE integration into Joomla based on the plain text editor. More configuration options are planed but I'd like to share this first version with you.
I just created a project on gitHub: ACE Content Editor Plugin. It is a good idea to get the plugin from there since it'll provide the latest version. You can check the download page too: Download Area
