You can download our latest version at the SVN Repository:
https://svn.typo3.org/TYPO3v4/Extensions/t3editor/branches/t3editor_codecompletion

Use your TYPO3-account to log in.

We refactured the code and made some performance-improvements too. Last but not least we integrated several important features which i would not like to miss.

Check them out: (this is revision 63 of the codecompletion)

Now there is still a lot of work since we have to create the whole xml typoscript reference out of the html-tsref. If you want to help, or have any ideas how this could be automatically done you are welcome!

quite simple, eh?
if you were using an additional title-field by now (just as i always have), you could use both fields and make a switch.
