Yes, sounds good to me for first implementation. For now I would not
try to merge, just replace and emit the "preferences-changed" signal.
This signal should trigger any updates in the GUI that follow from the
( Only edge case I can think of is that if in the UI with profile
applied we change a notebook independent plugin, it would be nice to
sync back to the default profile. Or in general we should keep
notebook independent settings in sync between profile and default. But
that can wait as a refinement. )
Also UI options for profile can wait. I think we should be able to
switch profile for a running instance by replacing preferences and
emitting the signal as well. So adding a dropdown in the notebook
properties is easy. I'll have a look at that when merging your work.
P.S. as an implementation detail, please consider putting the logic
for loading profile specific preferences in the NotebookInterface
class, in a method called "finalize_notebook()" or something like
that. Logic is not specific to the Gtk interface, but could also apply
to e.g. the WWW interface.
