After listening to a long queue, I noticed that there were problems
re-realizing widgets after moving the footer to a different page (the
header might have the same problem?). I decided to fix this issue by
creating a new footer instance for each notebook page.
If I do the same thing for the page header then I can get rid of the
"move this widget from page X to page Y" logic AND allow pages to use
their own custom header AND allow for separate library and queue
filters.
