Highlighting with notes
It would be lovely to be able to highlight parts of an online text and attach a note (much as Diigo does). If these were then saved locally with a snapshot document, it would be possible to annotate documents in a much more useful way.

Annotation and highlighting does not work with pdf files or word processing documents, even when these are opened in a browser window. However, it is possible to attach notes (as opposed to sticky-note annotations) to a bibliography entry along with a pdf file or word processing document, and to view the notes while viewing the document in the browser window.
There are some other screencast tutorials that demonstrate Zotero's features and are worth checking out, too.
Thank you very much.
