Clicking the little icons each time (especially since they don't stand out from the text very well) is a bit tedious. I noticed selecting and typing automatically defaults to "revise". This is a great feature. Are there keyboards shortcut for adding a comment? The move text functionality is probably the weakest link. Why do I keep getting the message "Can't move content like that."? Also, it would be greatly enhanced with drag and drop ability.
