Upgrade StorageScreenshot versus Screen Capture
I'd like to second Doggie's suggestion of adding screen capture to Zotero. This would be especially helpful for sites driven by AJAX. For example, a conventional Zotero snapshot of Google Maps creates an HTML document with an embedded AJAX map. This is all well and good, but what if the hooks to the server change or the JavaScript degrades? The locally stored map will cease to function. An image screen capture, I believe, would be a stable alternative to a snapshot.
