When editing items in the right column, I use the keyboard to tab between fields. If Zotero in not in fullscreen mode or there is a long abstract open/maximised, the right pane does not auto-scroll up or down to to the next field that is selected outside the limits of the Zotero pane. This is a minor annoyance as I then need to use the mouse to scroll to the active field and this slows down editing.

Also, depending on whether you are tabbing down or shift-tabbing up, the author surname and first-name fields display in different positions. This is only cosmetic but I thought I would mention it as well.
