 * Proof General Short List of Things to Do for next version

-*** A settings configuration for Isabelle: add backwards
-    compatibility for older versions of Isabelle.  
-    Waiting for Isabelle to provide some easy version
-    checking.
-
-*** B Cleanup display during settings processing.
+*** C Implement optional arg to next/undo which doesn't update
+      display (so user can retain something else on screen)
 
 *** A fix display anomaly for Isar output with shrink windows:
     display splits window unexpectedly.
 
-*** B document and simplify proof-script-span-context-menu-extensions
-
-*** C Add output highlighting to minibuffer in proof-shell-message.
-    (Quite tricky to get text properties onto text in minibuffer...)
-
-*** X A more flexible way of choosing which instance of PG we want,
-    allowing matches on the buffer before choosing the mode function.
-
-*** D Isabelle PG: Non-blocking for .thy loading from .ML files.
+*** B Cleanup display during settings processing.
 
 *** B Generic adjusting of pretty-printer line width (currently
     implemented in several instances)
 
-*** D Make code robust against accidental buffer kills
-      by regenerating auxiliary buffers automatically. 
-
-*** D Bugs with extents: 
-      Sometimes probs if try to assert a whole file while one is
-      being processed:     (proof-set-queue-start end) call in
-      proof-done-advancing finds that queue span is detached.
-      Code is now robust for this.  But why detach anyway?

-*** C Extensions with semantic tokens
-      Look at the Semantic Navigator package.  Implements persistent
-      database of tokens.
+*** B document and simplify proof-script-span-context-menu-extensions
 
 *** B Documentation:
       Check new doc for hiding; add doc for dependencies, tracing.
       Moving spans; navigating through locked region.  
       Favourite menu.
 
-*** C Fix byte compilation
-      Problem with proof-ass macro mechanism -- gets expanded during compilation.

 *** B generalize from Isabelle's "atomic scripting" theory file mode
       to allow other instances which do not allow incremental
       processing of files in major or auxiliary file types.

 *** D ChangeLog generation still not right.  
       Probs: duplicated entries when runs several times in same day.
       Suggested fix: use rcs2log to generate the entire log, just take
       a sensible number of lines from it.

-*** B Add parameter for help function so HOL help works nicely
+*** B TESTING. 
+    - Add automatic testing mechanism to test user-level functions PG
+    - Test schedule for things to try with a new instantiation
 
-*** D Make tags support in lego.el and coq.el a bit more generic.
-  Use customization option proof-tags-support.
+*** B Add a new configuration setting for matching proof commands

 *** C make pretty printer line width altering generic.
   Make a generic hook (or hook-constructing macro) to adjust
   pretty printer line widths, a la LEGO.  Maybe find a better
   place to do this that in the proof-shell-insert-hook (should
