Status Bar Statistics Rated 4 out of 5 stars

This is a great extension! I have some feature requests:

* add/delete blocksets - to allow for more than 6, perhaps a GUI widget other than tabs for managing blocksets

* status bar display of statistics - to provide one-click viewing of time remaining in a given blockset (answers question: how much time do I have left for (e.g.) blogging?)

* XML export of blockset statistics - to allow exploration of historical usage data

Thank you so much for this addon!

This review is for a previous version of the add-on (0.4.1).
