When I clicked on the "Export to Wikimedia Commons" tab, I expected it to open a tab (as all the other tabs do), not send me off to a completely different website. The link should either be moved under the "More" menu (which is where the similar function of file moving lives), or next to the "Open in Media Viewer" button under the image. It's placement in a tab is both confusing and overly prominent (as this is not a feature that will be used anywhere near as often as other tab features). Otherwise, it is a great feature. Nice work!
