[Sugar-devel] [PATCH sugar] Add duplicate functionality to the Journal and enhance copy functionality

You're doing two changes in functionally independent parts of the code
and the changes are not interdependent. It would make sense to split
them into separate patches.


> This will replace the keep button from the activity toolbar.

"This functionality"? Or perhaps "is intended to replace"? After all
this patch doesn't actually remove the Keep button.

Is there a reason we use set_icon_widget() instead of passing the
keyword argument 'icon' to ToolButton()? (Mentioning this because you
add a copy of the above code for the Duplicate button)

Factoring out the new code into a method _refresh_duplicate_palette()
would fit the existing code better.

If we log the entire exception, we don't need to include the error
message in the format string.

For consistency and robustness, please always use tuples with the
formatting operator, even if it's just a single parameter (=> singleton
tuple).

I still don't like the code duplication, but hopefully we'll clean that
up later.
