We could do a badge with Zotero red background and white Z. That would be a very easy change. It wouldn't be exactly perfect in terms of our branding, but there's only so many pixels there anyway, and the other option is to reprocess all toolbar icons to include a more faithful Z

This seems to have been dropped. Badges were added in 2783724, but then that change was reverted in cd6d45a. Any chance the badges can be re-added since no images were proposed?
