Hey Tobias,
I was able to do some testing this morning, and all in all it works very 
nicely.  Great feature!  I do have some minor observations...

* tsLoader.php uses "<?" to open the PHP script rather than "<?php".  On 
servers with short open tags disabled, this means the script isn't 
interpreted as PHP at all. This messed me up for a while in testing 
because the descriptions weren't ever filled in and I suspect Steffen 
may have been having the same problem.

* In talking to Olly, there are currently some IE problems but he's 
preparing an updated patch for that.

Once those are addressed, you have my +1 on testing for alpha1. There 
are also some improvements that would be nice in the future, but aren't 
at all critical for alpha1.

* t3editor doesn't load at all for me in the current Safari release or 
in Webkit nightlies. I do get the checkbox at the bottom to deactive it. 
It's a graceful degrade though, as nothing breaks, so I'm fine with it 
for the alpha release.

* It might be nice to have some visual indicator when the code 
completion list wraps back to the start.  I can see myself scrolling 
forever and not realizing it :)

* In addition to the return key, should both tab and right arrow trigger 
code completion?

* Single lines of TS work great but multiline properties don't trigger 
any code completion. I can see how this wouldn't be trivial but if you 
can pull it off, it would be a great feature :)

lib.textCObject = TEXT
lib.textCObject.value = Hello World

vs.

lib.textCObject = TEXT
lib.textCObject {
	value = Hello World
}

Off to review code now... Thanks!
