Is it possible to add zoom options to this addon?

Zoom page in sidebar?
Anyway, all sidebars are provided by Firefox itself (see "Load this bookmark in the sidebar" checkbox in bookmarks properties) or by another extensions, so this is Firefox bug...

And I only can try to override built-in zoom mechanism to handle focused page – all other ways are too complicated.
