Interested on a free WordPress IDE for coding?

Im a developer and as i havent found any free IDE for coding WP with syntaxis coloring and autocmplete i am developing my own one.
Im wondering if could be interesting that i share my IDE (for free).

What do you developers think?

Any editor with PHP and HTML highlighting will do that considering WordPress is – PHP and HTML.

But no all editors offers WP autocomplete or WP highlight, thats what im talking about.

Is there a Coda plugin for it? I know they have on for Drupal.

I recomend you Codelobster PHP Edition.
It’s most powerful among free code editors.
Some advantages of this editor are: intellectual autocomplete, FTP,
folding code, navigation with Ctrl for all links and descriptions and
incremental searching
Important feature of this editor is presence of special plugins for
Drupal CMS, Joomla CMS, Smarty template engine, JQuery library, CodeIgniter framework,
CakePHP framework, Facebook social network and WordPress blogging platform.

Also i want to pay your attention to the option Portable
CodeLobster - Free portable PHP IDE with support Drupal, Smarty, WordPress, Joomla, JQuery, CodeIgniter, HTML, CSS, JavaScript, CakePHP, Facebook, Symfony

I use Panic Coda (on Mac)
Otherwise try Notepad++
