Short feedback (generally applicable to any proposal):

1. Fill in complete template.
2. Try to describe what you want to do ("Less ominous warning and more
  helpful help icons" does not tell me much)

Directly to your proposal:

You write about configuration page, where you want to store
configuration values? I think this itself is separate project which
will consume quite a lot of time (well we were thinking that user
preferences would be separate project for GSoC).
