Sounds very cool. Did you manage to acquire SVN access?

I haven't really used the CodeCompletionInterface myself, but since the 
completionbox is implemented in the editor plugin I doubt you will find a way 
to changes to it.

Perhaps it's my lacking imagination, but what would you do in the main thread 
while doing CC lookup in the work thread? Any additional typing would 
invalidate the running lookup and potentially cause a new one. The only thing 
I can think of that you might want is the ability to stop the CC work if it's 
taking too long - but this shouldn't happen. If code completion regularly 
takes more than a few seconds people will undoubtedly stop using it. What 
kind of computation times are we talking about?

Much as I hate to put in more options, if the template code completion ends up 
adding alot of time to CC lookup, perhaps we should make it optional. This is 
a bad idea in general, but since the usability of the feature will vary with 
the machine spec, I think it makes sense in this case.
