One thing that would be interesting for us is better handling of 
relations between annotations.  Right now it is very difficult to have 
annotations that reference other annotations, e.g. for syntactic or 
semantic relations between text segments.

We currently use Callisto (http://callisto.mitre.org/) for some 
annotation tasks where we need such "chains", but would much prefer to 
be able to do it in UIMA.

A special case of this are annotations that are used solely to relate 
other annotations, but don't themselves correspond to a text segment 
(maybe we should even derive from TOP instead of Annotation as "begin" 
and "end" are not really meaningful). These would need to show up in a 
list of annotations, even though they are not "in the text", and we 
would need a way to add an annotation without selecting a text span.
