Hi Will,

For the first question, I think importing the other plugin's preferences is
not the right way to go. What you want is access to the "go_page_today"
action. Let the journal plugin figure out how to do that. This way you are
much more robust to changes in how the journal plugin works internally.

Probably should have a formal interface to access actions defined by
another plugin, but this will work:

    go_page_today_action = window.ui.actiongroup.get_action('go_page_today')
    go_page_today_action.activate()
    page = window.page

Thus you only use the "public interface" of the plugin that shows in the
user interface and automate that. A secondary benefit is that you don;t
even have to know who provides this action. If someone develops an
alternative plugin that supports this action, your plugin will still
collaborate.

If the journal plugin is not loaded, this will fail. Probably it is good to
catch that case and show an popup that tells the user to also enable the
other plugin.

For debugging I myself just throw in a bunch of "print" statements. Of
course unittests help to reduce the amount of re-starting you need to do to
check functions :)

Regards,

Jaap
