does Zotero auto-save?
I don't see a "save" button in Zotero, so I assumed that it auto-saves. However, I've now lost my notes several times because once I navigate away from a given article to another one, my notes don't get saved. Any ideas?
(Also, there's no need to click the sync icon manually. Just leave auto-sync enabled in the Sync pane of the preferences, and Zotero will sync 15 seconds after you last stopped editing.)
