I thought it was a specific requirement of the code completion interface that 
it supported multiple clients?  I worked hard to include that.

At the moment, I have implemented automatic syntax highlighting of completion 
items as they would be if they were inline.  This works for all highlighting 
schemes.  Without kate supplying the delegate, we would lose a useful 
feature, or have to expose the data and force apps to write code which will 
certainly be duplicated.

I'm waiting to see what David Nolden thinks, he was in two minds at the 
kdevelop sprint.  Maybe filtering and sorting can move to the client app 
without too much drama, but then you definitely lose supporting multiple 
clients.

Certainly I don't want Kate to end up with something unmaintainable, but at 
the same time I'm keen to see it support complex needs (eg. kdevelop)

Cheers,
Hamish.
