     exception like that, *perhaps*, to abstract away exceptions raised by
     event handlers, but it has no place in bb.build.exec_task
 
-- Leverage the python logging module
-
-- Convert bb modules to stop using the bb.msg functions.
-- Switch the messaging wrappers in the bb package to use the logging module
-  directly, as we'll be deprecating the bb.msg versions, but these should
-  stay around for the metadata to use.
-- Deprecate the bb.msg functions.
-- Should we use the logging module rather than print in the knotty ui?
+- BUG: if you chmod 000 local.conf, it silently doesn't parse it, when it
+  should really fail, so the user can fix the problem.
+
+- Audit bb.fatal usage - these should all be able to be replaced with
+  exceptions
+- Add deprecation warnings to the bb.msg functions
+- Figure out how to handle the ncurses UI.  Should some of our logging
+  formatting stuff be made common to all of bitbake, or perhaps all UIs via
+  the UIHelper?
 
 Long term, high impact:
