+--------------------------------------

 * Fix bugs and improve code and documentation
   Based on user feedback.  
 
-MEDIUM TERM
------------
-* Add an example instantiation of Proof General
-  using no prover-specific extensions (perhaps for Isabelle)
+* Queue manipulation improvment: allow to extend or reduce
+  during processing, with fewer "Proof Process Busy"
+  messages.  
+
+* Font-lock based on annotations in proof assistant output.
+  Particularly: colouration for Isabelle variable names.
+
+* x-symbol support integration.
+
+* Isabelle PG: Non-blocking for .thy loading from .ML files.
+  (hopefully as happy side effect of queue improvement)
 
 * Improve process handling 1
