I'm starting to port KDevelop, and so far have found the api to be ok.  I'm 
now looking at using the new moving range feedback, and I'm concerned that we 
will need multiple feedback objects at times (given we have many plugins, it's 
likely that more than one would want to use the moving ranges).  We could work 
around it by making our own feedback class that distributes feedback to a list 
of interested classes, but I'm wondering if you would consider allowing 
multiple feedback ranges in the api.

Thanks,
Hamish.
